4 weeks - 13dpo, side & lower back pain

Amanda
I had a very early miscarriage or what I think was a chemical pregnancy in October. I found out Wednesday I'm pregnant again, yay! I have been getting side/ lower back pain here and there all day it will be sharp then go back away... Some lower abdomen cramps as well always one sided for a couple days now... Is this normal? I'm praying this is a sticky baby - I didn't have the side/back pain last time.
I keep testing and making sure my line is looking okay... Here are my tests ... Does this look normal? Today's doesn't look any darker than yesterday. I know I need to chill out but it's hard with the pains. It's not sever but def noticeable.
