Good morning cramps pregnant woman normally feels around the time of her period during pregnancy does it has to be every 4weeks when her period is due or it could be a little late for eg. instead of getting it 12 weeks is it possible to get it 13week?

Because of the significant changes in female hormones during pregnancy, there should be no monthly cramps or bleeding. If you are experiencing some cramping at week 12-13, talk to your OB. They will typically check the baby with Ultrasound and make sure everything is OK. They may recommend bed rest or less activity, especially if the cramps are accompanied by bleeding.
