This would have had to occur around the same time as ovulation. This occurs approximately midway between periods. Every woman's cycle is different so it would be hard to know how successful you have been.
Yes.
VERY. Its happened to me too many times.
If there was unprotected intercourse in there somewhere then yes.
This is not a sign of pregnancy. If you have missed your period and have had unprotected intercourse you should take a pregnancy test or see your doctor.
Hi Yes there is a chance you could be pregnant. Perform a pregnancy test 3 weeks after you last had intercourse.
If you had unprotected sex you could be pregnant.
You can tell if you're pregnant two or three weeks after unprotected sex.
The vaginal irritation can be a infection and not related to any pregnancy but if you are late and have had unprotected intercourse, there is a risk.
The only thing your girlfriend could be pregnant from is unprotected sex.
Yes: If you take a store purchased test before atleast two weeks after the unprotected intercourse, you could indeed be pregnant. I would suggest waiting atleast 2 weeks to take a test.
If you have had sexual intercourse with someone, then you could possibly be pregnant. If not, then you aren't.
No, unless you have had unprotected sex since then. Please remember to protect yourself. Always wear a condom.
