I'm about 4-5 weeks and have also been experiencing cramps. I've had them for about 2 weeks and they feel very similar to bad period pain. From what I've read, they're normal in the first trimester.
I'm currently lying in bed with a heat pack hoping It'll give some relief and help me sleep with it!
Bad cramps as well as a morning where I fainted in the shower.. Hoping tomorrow is much better 💜
