Losing weight- cause for concern?

Hey friends,

So I am about 10 weeks pregnant, and we are so excited to meet our little I was taking a medication that is important for my mental health, and I gained about 100 lbs on it over the course of 5 years. I have since switched to a medication that I was on for 5 years prior to that, and have lost about 30-40 lbs since November of 2022. I know that it is related to the medication, because my weight shot up 100 lbs quickly after switching to the last one. I am a bit nervous though! I am eating plenty (1800-2200 calories per day), and walking for 30 mins per day. The thing is, I have lost upwards of 6 lbs since I tested positive for pregnancy. I’ll definitely discuss my concerns with my doctor. I’m just worried that this will negatively impact our baby! Looking for words of support. Thanks
