Normal cramping?

Kal

Hi ladies, I’m a new first time mommy and I am exactly 5 weeks. Tonight was the first night me and my hubby had sex after finding out I was pregnant, almost 2 weeks ago. Yes I know they say sex is fine but I was of course worried about everything as a first time pregnant woman would be 98% of the time :) anyhow, since then (about an hour and 30 mins) i’ve had some cramping on my left side, and an overall ache in my uterus. Is this normal? Has anybody else had this happen to them? Just needing some reassurance! Thank you :) Congratulations to all the new expecting mamas and our summer babies ❤️
