Hi Netti! I just found this thread. I was experiencing the same as you yesterday and Sunday with the dull AF cramps!! I just checked my estimated due date and I am 2 days behind you, so we must be going through very similar feelings at the moment. I also read something about the corpus luteum becoming a cyst - for everyone who is pregnant, and that can cause the pain in early pregnancy. it is nothing to worry about as long as there is no bleeding. Scary feeling though when you have just found out you are UTD!!
