Early miscarriage

Tori

Has anyone ever had an early ultrasound and was told the baby wasn’t measuring correctly and to expect a miscarriage, and everything turn out okay later? I haven’t bread or anything just bad cramps. I’m supposed to be 6 weeks but sack is measuring about 3-4 weeks.. I go back next week for another ultrasound to see if baby has grown any. I’m just so upset already, and it suck just waiting to miscarry..
