Belly button and abdominal pain after I to have sex

Have no idea WTF is going on me and my husband were getting into our sex and all of a sudden my belly button started hurting really bad then my Abdomen. Not really sure can it hurt being pregnant it felt like my belly button being pulled from the inside out. Could it be like my uterus being low? Gonna make an appointment just wanted to see either this has ever happened to anyone else and sorry it's TMI
