Hey ladies

So I did gentle yoga this morning and was mindful of my poses. I didn’t do any twisting nor did I push myself at all. Afterwards I got a dull achy cramp coming on and now it’s not going away. It’s not worse it’s just there. I layed down for a while and I’m about to take a warm shower but it’s just there and worrisome. I’m 4 or 5 wks (blood work today will confirm) and just found out a few days ago. Should I be concerned? I am not bleeding at all.
