Hello I was wondering if I had sex one day of one of my fertile days and ovulation day could I be pregnant and when can I test?

If you have unprotected sex at any time, pregnancy is possible. If it's on a fertile day, then it's very possible. Test when your period does not arrive, most tests are not very reliable before then.

If you're right about your fertile days and ovulation, yes, there's a good chance you could be.

Most women have no idea when they ovulate, and what's normal for many isn't normal for all. Any time you have sex you risk pregnancy, even if you're using protection. Women can even get pregnant during their period, it happens more often then you think.

So in short, if you had unprotected sex on your most fertile days, then there's a very good chance that you are pregnant.

Wait until your period is late then try testing. Use first morning urine for accuracy.
