Hi, so I am 18 weeks and 1 day today. :) I have been cramping a lot lately! My cousin is a nurse and also has 3 kids. So I talked to her about this first. Ok, my back has been KILLING me! Like, it's hard for me to get up. Doesn't help that I am pretty big already. And my cramps will come (in my lower abdomen, like around where I would get menstrual cramps.), and last for about 2 minutes, then go away and I will have another one a few minutes later!! She started having B-H at 16 weeks with her 2nd baby, so it's possible to get them this early. But can someone with experience about them tell me if this is what the cramping is?? :) Thanks!!
