Hun I'm not really sure but I do remember with both pregnancies having my belly drop at around 35-36 weeks, and also getting some severe pain in my vjj! It was So painful wiht James I remember walking around the shops pushing Iz in the stroller and I was bent over double in pain, Im sure people thought that I was in labour (I wish!). Anyway I think it is probably because of the weight of bub and they might be heading south and getting ready to engage, but I don't think it means labour is imminent! Can't believe you only have a few weeks to go!!
