Can’t lose the baby weight!

I’m almost ten weeks PP and I can’t seem to loose ANY baby weight. After labor I lost ten pounds, my baby was only 7 pounds. I see posts all the time of women loosing crazy amount of weight within just a couple weeks after birth ( like 20 pounds lost in 2 weeks PP). I’m starting to get concerned that I am having thyroid issues as I’m struggling to loose weight and my grandmother has hypothyroidism, along with both my mom and sisters having tumors on their thyroids. I am exclusively breastfeeding, eat a healthy diet and take an hour long walk everyday (although some days I only eat once or twice a day- no appetite and super busy) I am so confused! I’ve read that some women don’t drop weight due to hormones while breastfeeding and that once they wean off they start to shed the pounds. Just curious if any other mommas experienced this and what their story was. Thanks!
