Hi, I had sex on my bday dec 22 with my bf. We didnt use protection that day. On dec 26 i did get my period it was normal, now that my period is due tomorrow I've been very stressed because i haven't gotten my normal pain ( left rib would hurt) my back on my whole right side hurts, my nipples are very tender but dnt hurt when i shower, my tummy been hurting on and off, and i check my cervix in its mushy. Any suggestions?
