Cramping

I’ve been having Braxton Hicks all the time since about 30 weeks. I’m 32 weeks today and the last 3 days I’ve been very crampy feeling. Every time I’m up doing anything for more than like 30 minutes the Braxton Hicks will return. I was nervous I lost some of my mucus plug last week and had called my midwife but she said not to be concerned unless there was blood (which there wasn’t). I haven’t had any issues having BM until today and I keep having the urge to go but as soon as I sit down and try to I instantly start having cramps. I have tried 3 times today and I know I’m not constipated because I just went yesterday and I had been crampy but my stomach wasn’t literally cramping up when I had my BM. I’m curious if anyone else is having menstrual like cramps...? I have my 32 checkup tomorrow so I will definitely be talking to my midwife about it but was curious if others are feeling these pains?
