Hi Kafer!
Welcome and if you like we can carried through this journey together.
I too am about 4-5 weeks.

As for the cramps. yes as long as they arent combined with bleeding or extremely painful it is normal.
I have had dull cramps - had 1 week of spotting which ended yesterday (makes me wonder if it was like aperiod???).

With dd #1 i had cramps a lot the first trimester and i called it renovating! lol.

Dont worry and PM me if you want to chat.
