Hi OP. I can really empathise with this. Were you on mounjaro before you got pregnant?
I was and I had lost about 2 stone on it, I came off it a few months before getting pregnant and I have seen my weight jump up by much more than it should in the first trimester. I'm 18 weeks now and I have gained about 9kg.
I totally get the anxiety about it - I'm the same - and I was definitely overeating because my appetite came back, with a vengeance.
I have just started trying to cut down a bit, but I know all the advice is not to diet whilst pregnant, so I'm trying not to be extreme with it.
The main thing I am doing is trying to cut out junk food, biscuits and cakes, and swap them for healthy alternatives - greek yoghurt, lentil chips with guac, cheese on wholegrain crackers, chicken breast, fruit etc for snacks. I let myself have as much of this stuff as I need to fill me up, because it's really important when you are pregnant not to deny yourself.
I'm a bit concerned that you are calorie counting - how many calories are you having per day? It's probably not the best idea whilst you are pregnant, although I completely get the temptation to do it, you need to be listening to your body and if it needs more calories that's OK - just make sure it's wholesome food and not junk.
You also need to be careful about going straight back on the mounjaro after you give birth, especially if you're breastfeeding. I won't be going back on it for at least 6-9 months, even if I gain a lot of weight.
These things just need to take a backstep whilst you are pregnant. I have to keep telling myself the same. I was so happy with the weight I'd lost, but honestly, it's more important now that the baby and my body has the nourishment it needs. As long as you are eating good food and getting a bit of exercise, you just have to let your body do what it needs to do - we might gain quite a bit of weight, but that's something that we have to live with. We can always lose it again after the babies are safely here.
Let me know if you want to DM as I think we're in a similar situation xx
