I had unprotected sex while i was ovulating and he pulled out cum on my stomach then put it back can without wiping what are my chances of being pregnant? it was day 7 of ovulation?

Ask as often as you want. The answer will not change. The risk is not zero but not high. I can find no studies for this type of exposure to quote a risk. If you are within the ~72 hr window for most OTC emergency contraception consider using it.

If this happened less than 72 hours ago and you do not wish to be pregnant, take Plan B emergency contraceptive. If you do not wish to be pregnant, use contraception all the time, every time. Consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine,
