Ok, well i had sex on May 10th, like 2 days after my period. The condom broke. About 2 weeks later my back started hurting and still hurts to this day. Around the 4th or 5th week i almost threw up at 3am and felt sick on and off at random times. My appetite would also appear strong and weak on and off. I was supposed to get my period this week(6/5~6/11) but its 6/11 now and it never came. I went to the clinic to get tested on thursday and it came back negative. Could it have been too early? Should i get a retest later? I need advice on if i should just forget about it and move on or stay concerned.
