I've just come home from Sainsbury's and having major worries. On taking my shopping to the car, my trolley wedged in a pot-hole, stopping it in its tracks and rammed the handle bar into my bump. I jabbed it pretty hard just above the belly button. I'm 20 weeks pregnant and have already had one miscarriage. Tummy's all a bit achey. Does anyone know how well the baby is protected at this point? I have my scan on Thursday, should I wait til then to do anything about it?
