My 21 month old baby girl is breaking my heart 😭

Ever since I got pregnant My baby girl is soooo clingy to me! She won't leave my side and wants me to carry her the whole time Β  (which my mom told me not to do in the first trimester since it could hurt the baby..)and if I tell her no about the smallest thing she flips her bottom lip and does the SADDEST pout EVER!! It seriously breaks my hearts but I need to be careful since I wasn't last time and had a miscarriage at 10 weeks 😭😭😭 And I was telling her about my daughter and she said that kids feel this kind of stuff. They get jealous and feel left out so they get super attached to mommy. I feel horrible not picking her up and holding her. Anyone go through something similar to this? Can ANYONE give me some advice / activities we can do together to make her and me feel better about this whole distancing her thing at least until I get past the 12 week markπŸ˜­πŸ™πŸΌπŸ™πŸΌπŸ™πŸΌ
