good new is you had your period meaning you are not pregnant.
Yes. Sort it out mate.
If you had unprotected sex then there is a high chance.
A normal period usually means no pregnancy, if you are unsure take a HPT.
Yes. The number of days your period lasts has nothing to do if you can get pregnant or not.
possibly
Yes
Assuming that you have been having unprotected sex, then you sure could be, unless your periods are always irregular . . .
You shouldn't be using withdrawal in the first place, because it's NOT birth control - and yes, you could be pregnant!
The period is the time of expulsion of the unused egg. The body then waits for the next ovulation, which is usually 10-14 days after the end of the period. Therefore, it is very unlikely to get pregnant 4 days after one's last period. However, it is still possible.
Personally, sore and itchy breasts were my first symptom. Even before I missed my period. Good luck!
Four weeks would be near to the next cycle. Considering that the average woman has a 28 day cycle ( give or take a few days) this means on or about day 14 she would ovulate. In that time frame of day 12-18 she could get pregnant since sperm can live in the uterus for 5-6 days.
