frustrating

So sex supposedly helps bring on labor but every single time my husband touches me now she goes wild in my belly and it 100% kills the mood! This had never happened in past and it's so obnoxious. She's not just readjusting either...it's as if his touch signals an in uterine rave party. The first few times I thought it was funny but now it's just frustrating especially when I want her out more then anything!
