Over the last 8 months Ive gained 30 lbs (really over 3 months feb-apr) . This was the first red flag along with constant fatigue, coldness, nausea, dizzyness and depression. Doctor did TSH , T3 and T2 labs, I was within normal range. After researching on my own, I decided to go off birth control. Within a week I felt completely different, my energy is back and my period which was getting longer and longer , 37 days on birth control, went back to my normal 28 day on the dot cycle. Is it possible that I have a slight hormonal imbalance? I read about estrogen dominance and how birth control can exaggerate that imbalance even more. How do I find out? And what else should I take into consideration? Thank you
