So, on May 21st, I had sex, condom broke, no actual cum went inside me except pre-cum. May 22nd, took plan b just to be safe. On the 25th I should've been ovulating already. anyways, skip to today. I am currently 8 days late on my period, I feel bloated & nauseous with slight head pressure. No signs of bleeding/spotting..no actual cramps yet. Very slight ones rarely. Normal? or am I freaking myself out? I also worked out today for the 1st time ever so maybe a factor?? Advice???
