Hi, I am 17 weeks pregnant and I know they say its normal to have some cramping during the pregnancy when everything is stretching but sometimes it wakes me up at night they get so bad its a mixture of really bad menstrual cramps and having to make a bowl movement, is this normal? There is never any blood so Im not sure if its the baby growing or if there is something wrong Im scheduled for a sonogram on Nov 14th but the worrying is driving me nuts..
