It is common to spot during your pregnancy, but you might want to go to your doctor and have it checked out.
yes
a cat will be pregnant for about 6 to 7 weeks
They count pregnancy from your last menstrual period not from when you actually had sex and conceieved. So if its been 5 wks since you had sex and got pregnant but you had your period like a week before that then you'd be 6 weeks pregnant. Or if you started your period 2 weeks before you had sex then you'd be 7 weeks pregnant.
Yes.
No, I don't think so. But you can still check with your doctor.
If you are 7 weeks from your last period, you are seven weeks pregnant, 3 weeks pregnant is before you miss a period and you would not have a scan then. If you are seven weeks and there is no sign of a fetal pole it appears that the embryo may not have developed and you will miscarry soon, I am sorry.
Technically, 10 weeks pregnant.
You aren't if you were 7 days late you would be around 5 weeks pregnant. The way an estimated due date works is you start from the first day of your last period. Unless you are 14 weeks pregnant and got your dates confused or had bleeding that you thought was a period but was something like implantation bleeding.
You did not get a period while you were pregnant.
Two weeks after you have your period is typically the most likely time to become pregnant.
You ovulate two weeks before menstruation - thus the soonest you'd skip a period is that first period, two weeks after you get pregnant.
Pregnancy is calculated from your last LMP, rather than the date of conception. So, if your last period was 7 weeks ago, you are 7 weeks pregnant. You actually conceived 5 weeks ago, around day 14 of your cycle.
