So my boyfriend and I did stuff 2 days after my period where his stuff went onto my vagina (no penetration). Then a day before my supposed ovulation we tried to have intercourse, he couldn't get it up though but there was pre, and it went against my private area (no protection). Now it's a day past when I suppose to get my period and my symptoms are headaches, nausea, dizziness, sore boobs and cramps a few days ago. Am I just really stressed or could I possibly be pregnant (even thought the chances are low)? ALSO I had some kind of small bleeding somewhat a little while after the things happened.
