17P injections, braxton hicks?

S

I’m 18 weeks and I’m getting 17P injections as I have a history of spontaneous pre term birth. I saw my nurse today for an injection and she was a little concerned to hear I was having Braxton Hicks last night and cramping this morning. Has anyone had a similar situation? I think it’s from doing too much. I’m on my feet a lot as I have a 3 and 4 year old and my husband works out of town a lot.
