Long post but need help

Last July I found out I was pregnant... ON BIRTH CONTROL. As expected, I miscarried. My significant other and I immediately stopped taking it and started ttc again in November.

I haven’t gotten pregnant since but I haven’t had a period for 3 months so I called my doctor and he said my beta is at nonpregnant levels, I have high LH levels and an ultrasound showed follicles on my ovaries.

I also took a pregnancy test Saturday and it was still negative (just to be safe)

He put me back on birth control 5 days ago. I’ve been having right sided pelvic pains that come and go since Monday (no bleeding). My boobs feel very full and sore (like when I was pregnant).

Giving our calendar should I take more tests or does anyone think it could be the birth control pill?

Yes I will call him but i didn’t wanna worry if it was nothing.

Any help?!
