I am 10w pregnant and have had normal cramping/ ligament pain all the way through. But I just started using progesterone pessaries at night as my progesterone level was only 9. After I insert the pessary I go straight to bed and within a few mins I get cramps that feel like period pain. It lasts maybe an hour and I struggle to get to sleep because of it. Has anyone else experienced this? I don't know whether it's just because it's working and being absorbed?
