That is what my contractions felt like when I went through preterm labor I would go to hospital.
I don't know if my comment posted or not so I'm gonna say it one more time. Go to the hospital. Like now. It sounds like contractions. I went through preterm labor during the Easter weekend and that's what the contractions felt like. Go to the hospital.
Go to hospitall or call your doctor
