I need some help. I have yet to have a period for June. My husband and I had sex on June 1&2, and on 15th, then on 18th I had raw egg white discharge and I also later that day had bright red bleeding after I wiped and it was only that once that I was bleeding. I had put on a pad cause I thought my period was coming. But I have yet to get it. I have taken two pregnancy tests because I feel off, nauseous, and crampy, and just not myself pretty much all week. Both tests came back negative and I'm lost. I am not 100 percent sure on when my last period was I believe it started may 8th but Im not 100 percent. That's my best guess. Any advice please?
