Hi Kaltiki,
Congratulations firstly !!!
I am 5 weeks tomorrow, and i've been having alot of AF type pains too, as well as what feels like a sharp stitch pain low down on my right hand side. It is good to read that others have it too, i dont remember having it with my other pregnancies, maybe now because im older my body is noticing it more and getting cranky with me lol
Good Luck for the rest of your pregnancy
