i had unprotected sex 17 days ago(on ovulation day), he pulled out. and i know there are chances of pre ejaculation. i have been experiencing small cramps in my lower abdomen, and my lower back is sore. Breasts are sore as well, but no nausea.My stomach feels bloated But my period should have came today, but nothing yet. i took 2 pregnancy tests on the 2 week mark (4 days before my period should start) and both came out negative. No spotting or pink when i wipe. so i haven't had implantation bleeding. But i have had dishcharge the past few days. Could this just be pre PMS symptoms or am i pregnant? I've been stressing a lot about this.
