Am I Out?

I got a faint positive on a first response early response on the day before my period - I tested because I was cramping pretty bad which usually indicates the start of my period but I cramped for about 2 hours and AF never showed. and then on the day of my missed period I took a regular first response and got a negative result. Am i out? I feel like I should be having a glowing positive if I’m missing my period but maybe I’m wrong. I’m now 2 days late, we BD on my ovulation day, and I’ve had horrible mood swings, sore breasts/nipples, extra discharge. No sign of Aunt Flow coming though, I’ve had no breakouts and I haven’t had any cramps for 2 days. Ugh. Anyways. Help!
