I'm only 7 weeks right now and i have been having the same thing, i talked to my doctor about it and she said that it is probably my uterus stretching. Nothing to be worried about.
Thanks you guys. I feel less nervous now. My friend also told me she too had some cramping in the beginning of her pregnancy so now I can keep calm until I see my doctor today. I will keep ya'll posted on the outcome :-)
I am pregnant with my second, 9w 4d, and I myself had some mild cramping and still do from time to time in the morning, I think it may be everything stretching and every pregnancy is different, I think you will be ok as long as there is no bleeding along with the cramping, it should subside and come from time to time when baby and body grows, I hope this helps and good luck at your appointment
