I fear I am ovulating....and I had unprotected sex with my husband and he and I climaxed together. Usually we do not use protection, because I am sensitive to every method we have tried. So we usually use the "pull and pray" method. Although most times he does not climax at all during our intimate times.I have researched several ovulation calenders and calculaters online, and most say I am ovulating, and or, fertile right now. What are the chances of me becomming pregnant after just this one time?
