Heavy cramping and back ache 17w3d

S.K

I’m having bad cramping and a back ache as well as tightening in my uterus. At first, it was going away with rest and now the pain is present even when I’m not doing anything. I also lost a piece of my mucous plug last night. I know if can regenerate but was worried because of cramping too.

Has anyone had this happen so early?

*this is my 3rd child

**i have already seen a doctor but the just said it was too early to do anything, called it a threatened miscarriage, and told me to rest. He said medically, there is nothing they can do about it 😕 They won’t even check if these contractions are causing a cervical change.
