15 wks and I feel like my body thinks I’m 20wks!

Tru • Due early jan ‘19

First pregnancy so I’m still new to all these strange aches n pains...

I’m 15 weeks and my ribs feel heavy/possibly expanding, when I’m sitting, I thought it was still too early for this 😬

Also ab muscle separation!! When I lay down I have a big gap between my abs..

Anyone else have these symptoms???
