I'm confused...

About where to post this... haha
So I recently started incorporating strength training into my work outs (yay!!) and upped my calories from 1200 to 1300 a few weeks ago with plans to get to 1350 soon but within the past 3 weeks I've gone from 146-149 and stuck whereas before my plateau was 146 for two months which royally sucks. Anyway since adding strength and upping my calories I've gained an inch in my waist and an in around my belly button which sucks EVEN MORE!! I though strength would help shrink my inches not add to them I don't get it, before I was a cardio queen and it was working until my plateau. So any ideas on what's happening? I'm not very happy with this recent development, not like it's going to slow me down, but I am just so so confused.

Any insight would be SUPER helpful Thanks!
