I think I'm out for this month. If I am pregnant, I should have gotten a positive by now.

Is it possible to not get a positive until several days after AF is due? AF was due Saturday according to my calculations. I didn't use FMU with this test though nor was it a FRER. This was my first experience with a dollar store test. I wanted cheap tests just to satisfy my poas addiction.
I got a bit of spotting today. Just a tiny bit. It wasn't bright at all, just tinged pink spotting. :/ Didn't show up when I wiped at all, just a tiny bit on my panty liner then no more. I think it was over night. I'm so confused and bummed.
Still having symptoms. At this point, I'm beginning to wonder if I'm imagining things. Although, my favorite food is chinese and I couldn't stand it yesterday, that's exactly what happened when I was pregnant the first time. Boobs still hurt; still get random moments of nausea; head aches; still getting slight cramping on and off. I don't know what's going on in there. :/
