Relax or worry?

Well last cycle I had unprotected sex 4x during my fertile window using pullout. Had weird PMS symptoms I don’t usually experience, thought I was pregnant. Got my period on time but it was extremely heavy and had extreme cramps, both of which aren’t normal. Had a dream I came across a dead baby.... Anyway onto my current cycle I’m again in my fertile window and am extremely nauseous and not having my usual ovulation pain. Right now I feel a little anxious still and won’t feel better until I get my next period with my usual signs. Would you worry or just relax?
