Weight gain? Or pregnant?

K • dogs and wine. 🍷🐶

So I’ve been trying to lose weight.

I’ve been hiking (not everyday but enough), I’m eating pretty healthy. But my pants are getting tighter around my belly.

I’m having monthly periods but I’m in constant pain off my period and more so on my period on my left side. (I did have a cyst 6 months ago that is gone now)

But my mom was pregnant for 3 months and had normal periods with all 3 of her children. Could that be genetic ?

I’m only 23. Not ready for a baby. I plan on doing a store bought test but any advice ?
