Cramping but 5 days late

Had relations w/my husband the 18th, 20th, and 22nd unprotected. Only the 18th and 20th were during my fertile window. Last week I had one day when I wiped and there was a small amount of brownish mucus. Thought nothing of it because I was supposed to start Saturday. I’ve also started to get indigestion here and there. AF was due Saturday per the app, but it’s been a couple days off the last 2 cycles. I’ve had slight cramping since Monday and my boobs are now sore. I’ve also been bloated, and gassy. I don’t normally have the symptoms. It’s now Thursday, and still no period. I’ve gotten 3 BFN. Going crazy not knowing what’s going on!! Also, no I’m not ovulating, and yes I called my doctor and waiting to see if she wants me to come in.
