What to do?

48 days late.

Last period was Nov. 15th-21st

I've been feeling off lately.

Craving certain foods which I normally hate.

I'm tired all the time, back and hip pain.

SUPER sour boobs, any little movement or squeeze hurts so bad.

Tmi but... I'm hella gassy and constipated lately.

When I lay on my stomach in bed I feel like a big bubble? I guess. Like my lower stomach just feels weird.

I've taken 4-5 tests since my last period and they all say negative.

What should I do?
