weight gain after stopping bc

Kay • TTC # 1 💜 firefighter wife 🚒 Labrador retriever mom 🐾
I stopped taking bc pills beginning of May after being on them for about 13 years. Hubs and I decided to ttc and wanted to make sure my cycle went back to normal - which first cycle was right on time.
Anyway, in the 6 weeks I've been off bc, I've gained about 10lbs. My diet/exercise regamant hasn't changed. Has this happened to anyone else? Debating if I should see my dr... but is that a primary apt or ObGyn apt?
