hi i'm 29 years old i'm 9 weeks pregnant and one week ago i went to see my ob and he gave me this vitamins and also some nausea pills.since i started taking this pills i have constipation.2 days ago i went back to the doctor so i can get something for my constipation all he gave was fiber and a stool softner.yesterday i woke up took the fiber and the stool softner and had a bowl of cereal with milk.one hour after that i got this awfull rectal pain and cramps that made me sit on the stool for an hour hoping that i can get rid of my constipation but it wasn't like that all i had was a brown discharge and since then everytime i eat or move i have to go sit on the stool and have this awfull cramps and this brown anal discharge.what can i do the pain is unbereable and my rectum hurts so bad.i was thinking as my last alternative is to have an enema is that safe?any advice?
