Cramps.. lower back pain..

I know this gets asked a lot but I’m new to this and wanted an up to date response 😊 so basically, I found out yesterday I am 5 weeks pregnant. Super excited, but obviously know it’s very early. I wondered if anyone else has been experiencing a mild dull type of ache in there lower abdo? Sort of like period pain but more of an ache and not as intense? Also accompanied with a mild lower back ache. I have no idea what I’m suppose to expect being a first timer 🤷‍♀️ so any input would be great. Oh- and btw, no bleeding/ spotting at all. Thanks x
