Advice? Could I still be pregnant or just late?

I was supposed to have my period between 18th and 22nd September. AF did not show. My period has been very regular since I stopped birth control in January. This is our first month of TTC. On the 24th I experience pinkish blood, sort of slimy for 1 hour, and then it disappeared. Throughout that night I had bad cramps and nausea. Since then I’ve had a change in appetite. When I eat Maltese’s (chocolate) it kinda tastes like old chocolate cake batter. Garlic smells so strong.

Small things, like that. But every night I have extremely detailed dreams. They feel so real and I’m sleeping like 12 hours and still feeling a little sluggish.

I’ve been doing test for 3 weeks now and a few came back faint line but since the cramping I’ve had no positives. My ovulation tests are also negative.

My bbt is ranging from 37•c - 36•c mostly low.

I have had some hot flushes as well on and off.

It’s a Covid lockdown for me, so my doctors are only doing phone consultations. I’m unable to get a blood test until they reopen. Which I’m not sure when that will be.

I also take regular medications for BPD. Could this be effecting my cycle?
