I am not a doctor, but this happened to me. I started spotting only 7 days past ovulation and when I called my fertility clinic at 10 days past ovulation, they advised me to start progesterone, which led me to believe I still had a chance to be pregnant. I continued to spot for days 10 and 11. However, 12 days past ovulation (two days after starting progesterone) my period came. Although I think it's still possible to be pregnant with spotting and starting progesterone that late, if the spotting is related to your uterus lining breaking down, it is unlikely. I have a history of starting my period early despite having good progesterone levels, but if you do not have this history, it's possible your spotting is implantation spotting.
Start counting your period from the day you see the spotting if this happens every month. You could also do basal body temperature which will pinpoint ovulation, or use the Billings method.
This is spotting, it's light bleeding that has mixed with your discharge. This can occur at the start of end of your period, or it may be spotting for another reason such as ovulation spotting.
The corpus luteum secretes progesterone in response to luteinizing hormone (LH) released from the pituitary gland following ovulation. Progesterone is crucial for maintaining the uterine lining during the second half of the menstrual cycle and early stages of pregnancy. If fertilization does not occur, the corpus luteum breaks down, leading to a drop in progesterone levels and the start of a new menstrual cycle.
Spotting is normal before your period, it's just the start of your period as the uterine lining starts to shed. You can also get spotting after your period, or mid-cycle spotting around the time of ovulation.
Spotting during ovulation is common in most women. The only way to tell if your ovulating is by doing a ovulation predictor kit/test which you can buy from the pharmacist or off Ebay. This will tell you if your ovulating. To expand: The Ovulation Predictor Kits can be a good way to tell if you are GOING to ovulate, but during/after you've ovulated they are no good. The only way to confirm you HAVE ovulated is to make a chart of your Basal Body Temperatures (you take your temp VERY first thing at the same time every morning before you do ANYTHING else, even go pee) or to go to a gynecologist and have them perform an ultrasound to see if you've released any eggs. It IS common to spot a little during/right before ovulation, but heavy bleeding could signify something serious. If you're spotting you're either just about to ovulate, or currently ovulating.(It's about a 12-24 hour window for most women.)
The corpus luteum is the follicular structure that forms immediately post-ovulation. It is responsible for producing progesterone to prepare the uterus for potential implantation. If fertilization does not occur, the corpus luteum will degenerate, leading to a decrease in hormone levels and the start of a new menstrual cycle.
Progesterone doesn't start your period, it's actually the drop in progesterone that starts your period. Progesterone caused the uterus lining to build up, if pregnancy doesn't occur the progesterone level drops causing the uterine lining to break down - menstruation.

if you havent started your periods this is what it could be. If you have started your periods and this is occurring before or after you period is about to start it could b spotting if its possible it isn't spotting i would go seek a doctors opinion answer ovulation bleeding or implantation bleeding
Implantation Bleeding After ovulation the egg travels into the uterus and burrows into the lining of the uterus. For some women implantation will cause slight bleeding or spotting. This is called implantation bleeding. This is sometimes confused for an early period. What does implantation bleeding or spotting look like? Implantation bleeding, also called implantation spotting, does not look like a regular menstrual period. Implantation bleeding is scanty and usually pink or brownish discharge. Implantation bleeding or menstrual period? Implantation bleeding normally occurs a week to a few days before your period would normally start. Spotting that occurs around a week after ovulation is likely implantation bleeding; whereas, spotting that occurs very close to the time that your period would normally start may not be. A normal menstrual cycle generally starts off light and then gets heavier. Spotting can sometimes be the sign of an early period. If this is the case, the spotting will pick up to heavier bleeding. If you have spotting right around the time your period would normally start, it can be more confusing. You will need to take the wait and see approach or take a pregnancy test to determine pregnancy.
The typical length of time from ovulation to the start of a period is around 14 days.
The brown stuff is known as 'spotting' it is just blood mixing with discharge, it turns brown when it comes in contact with air. This is just the start of your period, you can also get it at other times such as at the end of your period or around ovulation.
