Preggo or Birth Control playing me for a fool (again)?

First things first, I take birth control. Last year, I had a scare because I was a month late (hpts came back negative). Went to my doctor and it turned out it was just a side effect of the pill. She changed up my dosage so that my period will come every month to prevent such a freak out. The pills worked great, I kept getting my periods every month, lasted 4 days tops and the cycles were VERY consistent.

Until now.

I'm currently 2 weeks late. I've gotten BFNs with the tests I've taken (I've taken 2). I'm not currently freaking out as much (or putting my hopes up) because, again, it might be my pill playing tricks on me. I do admit, I've double dosed a couple times during this cycle and my fiance and I have unprotected sex (no back up methods, and yes he comes inside). I've been driving myself nuts trying to find articles or people who've been in my position. I've had friends who've gotten pregnant while taking their BC. I've decided to wait until my next due period (which Glow indicates will be between the 10th -13th) to make an appt with my GYNO if AF doesn't show up again.

I just want to know if I should just test again,wait and if ANYONE has gone

through such a thing!!
