I may be having contractions but idk. it was every two hours I had a tightening feeling in my belly along with pain in my groin area that would last a short time and then go away. now they seem to be every hour and getting a little worse. could I be imagining or is this contractions? I'm 5 weeks before my due date but due to all the complications it may be possible. help?
