Some mild cramping might be normal, but if it is painful and doesn't go away, I would call the dr.
BTW, are you an OU alumni? I ask because of your user ID? If so, I also went to OU. There aren't many okies on this forum.
Take care and good luck.
I occasionally get gas pains. If there is any air in my digestive system, it causes some mild cramping until it's gone. Not fun. The first few times worried me very much until I realized what the cause was. You may want to contact your doctor though. They usually recommend calling them with any cramping symptoms.
call the doctors office and tell them you might be having a miscarriage. They can check with a blood test. Sorry for the sad news but, I had the samething happen at 6 weeks
