CD 37 no period and a bfn 3 days ago

This is my first month ttc since being off the pill. I had been pregnant before on the pill (missed a few pills and got pregnant). But I didn’t get a positive test until I was about 7-8 weeks (I miscarried around 10ish weeks).

I’ve been extremely bloated and nauseous the past few days. Typically nauseous in the evenings and super hungry during the day. I’ve been emotional and feel like crying all the time haha.

Any ideas? I know it takes a few cycles to get everything straightened out.
