WTH is going on?!

I’m so frustrated!! I’m on CD 48. Period is 2 weeks late. Completely skipped January. I’m so tired of getting BFN’s. Keep testing positive on opk’s. At this point I just want my period to come and get it over with. I went to OBGYN on Friday and she’s just as confused as I am. Awaiting blood results, but I’m trying not to get my hopes up. I don’t have PCOS, and my period has been pretty regular for the past couple years. I’m feeling really impatient and anxious. I just want to know what’s going on. Any ideas ladies?

TIA
