I just started having cramps like 15 mins ago the first 2 were like strong period cramps and since then I've only been having my normal small ones that I get when my uterus is stretching. Haven't felt anything like the first 2 since I got pregnant and I'm really worried I'm going to miscarry.. no bleeding or anything. Please let me know what you think or if you've experienced this. Thanks 🙏
