I was the same was terrible before 12 week scan then when everything was okay the thoughts went but then at times i would feel really bad pains I would wounder if I hurt my baby and start ringin my midwife up for a baby's heart beat monitor appointment to make sure my baby is okay in there .
I get sharp pains from picking my son up. You have to remember theres alot of stretching, moving and things going on in there. Try not to worry, unless pain is unbearable or blood. You dont wanna over worry yourself. But its hard not too. The worry never stops even when they are here!
I know exactly how you feel!!! Ill be playing around with my hubby and all of a sudden ill get sharp pains in my abdomin!! But so far nothing has gone wrong and my doctor says everything is perfectly fine
