These are very good indications of pregnancy. I would take a test to be sure.
Not really. Typically your ovulation "toggles" between the two ovaries and so your period may be lighter or heavier depending. Spotting or cramping comes later.
what does it mean you start to have a light pink discharge after your period
Spotting is just when there are small amounts of blood in your discharge. If this is just before your period then it is likely just the start of your period.
It is your body's way of preparing for your period. The cramping should only happen at least two or three days before you start your period. If you don't start, it may have been your body releasing an egg. The spotting, is very normal. Again, your body is preparing for your period.
Brown discharge is spotting, light bleeding taking time to leave your body and mixing with discharge. Spotting can occur as your period starts, or it can be a result of many other things such as mid-cycle spotting around ovulation due to irregular hormones.
unless the next month you miss your period and you dont have one no. Cramping and nausea come with your period
Go to your doctor immediately if you think you are miscarrying. If you bleed like a period, then there is trouble. Spotting is normal (within bounds) as long as it isn't enough to have to wear a pad. Cramping is normal. Discharge is also normal if it is brownish or pink, but not bright red.
Brown discharge, or pink discharge, is known as spotting. If your period is very light you may see a few days of spotting instead or you can see spotting leading up to menstruation. Otherwise spotting can be a result of hormonal imbalance causing mid-cycle spotting around the time you're due to ovulate. If it's a one-off nothing to worry about, but if it continues talk to your doctor.
cramps after a period are a regular thing. But having brown discharge?? You should probaly go see a doctor about it.
