18 Days late and 6 negative damn tests. Hellpppp

I’m literally losing my mind. 🤯 I have been having consistent period for the past year or longer, it’s always the first week of the month BUT February I did get my period the first week lasted 5 days then I got my period again on the 28th of Feb and also lasted about 5-6 days. We’re now approaching May and still no sign of a period, I’ve taken several tests one did show a faint line but then again maybe I just wanted to see a faint line lmao so I could have imagined it. Doctor won’t see me till May 1st. Symptoms i have been experiencing lately are— fatigue, heart burn (I never get that), gas 😷, I did have light cramps about 2 days ago, my back hurts like hell, occasionally I get light headed and I did notice an increase in my food intake. Also I’ve been having what seems to me as like the discharge while you’re ovulating.. was milky the other day now it’s just clear (not heavy).

Has anyone ever experienced this? I did have gastric bypass so I was thinking maybe since my body now absorbs things different etc that possibly that could be why the tests are showing up negative.

Thanks for your input babes. 💜
