Cramps are completely normal, nothing to worry about, I would be worried if you DIDNT have cramps. I had them worse than AF cramps for the first 6 weeks and it drove me nuts. For about 5 of those weeks I kept constantly thinking my period was coming any day now. They slowed down in the second trimester for me, but still come here and there, nothing for me to be concerned about.
Congrats on the pregnancy
