Cervix cramping

Jade

The past few weeks I have felt some strange cramping in or near my cervix. At 13 weeks I went to the ER for some bleeding and clots but it stopped a few hours later and they blamed it on the transvaginal ultrasound I had earlier they day. I’m 16.3 now also with a septate uterus. Anyone else having this issue or is it just growing pains I’m feeling?
