Ftm!! Breastfeeding question

I’m going to be a ftm and I’m 27wks on Friday!! I’m so excited for this baby even though I’m 19 y/o and I honestly have no idea what I’m doing but I’m just waiting and willing to learn and be the best mum I can be!!

Anyways, I haven’t been leaking or anything and I really want to breastfeed!! I have a thyroid condition (hypothyroid) that is meant to impact whether I can breastfeed or not but it’s meant to be perfectly fine to do it. Because the meds don’t affect the baby apparently idk. I’m so scared that I won’t be able to breastfeed it’s really scaring me. I haven’t been leaking and everyone I’ve talked to has said they were already leaking by 26/27 weeks!!

Any advice?? I’m so scared rn!! 🥺🥺😬😬
