Hello, my period was over a week late i began cramping severly and passed a golf ball sized clot.history of ehlers-danlos and miscarraige very worried?

Pregnancy Test: Greetings.Early on, it can be difficult to differentiate bleeding/clots from a period or miscarriage. Bleeding can also occur during pregnancy. Since you were a week late, I recommend taking a pregnancy test. If positive, it is important to get care ASAP to check for etopic/pregnancy complications. Especially if still having pain. If negative, see a doc if symptoms unlike a normal period persist.
