So me and my husband had unprotected sex about 3 months ago. I got my period late but it was really weird. Like it was really just spotty , usually the first two days I’m really heavy and then it’ll be medium it’ll last for about seven days and I was just spotty for seven days so I thought maybe I’m pregnant so after. I waited another week to take a test ,so I took a test and it said I wasn’t. I wasn’t pregnant! So I’ve been gaining weight, my boobs have gotten really sore! So I waited a couple weeks to take another test and still negative so I figured maybe it is because I’m just stressed out a lot so my period was late but it usually is so like no biggie! but I gained like 30 pounds! so yesterday I start my period and late in the night I go to the bathroom to change my tampon and I noticed these very large chunks , dark red/brown color.
