Hello! a few days ago I had my first sexual intercourse (previously only a different kind of pleasure). He has been taking vines tablets for more than 7 months. I will point out that I have never forgotten about any or delayed the time of its adoption. Coming back, the intercourse itself lasted a relatively short time, we did not protect ourselves additionally, and the partner did not end up in me. It wasn't until a day later that there were concerns about whether I was really pregnant? (Earlier, during the caresses, there was a few times a fear that nothing got anywhere and hence my oversensitivity may arise). Since yesterday, my lower abdomen has been slightly hurting and I have a problem with appetite (but this may also be a consequence of other stressful things). I realize that properly taken pills give a high percentage of effectiveness, but I still have a storm in my head. Should I stress myself in advance, or should I calm down because there is no chance of pregnancy?
