Is this normal pain

I havent been to work for 2 months, i came back around 16 weeks im currently 18 weeks. when i get off work im incredibly sore. i expected to be a little sore b/c i havent been there,so i haven’t really been doing anything in my first trimester. I put it off as my bodys not used to moving like that anymore. i work at my own pace and take breaks often, but when i get off work im so sore to the point I cant walk normal. the only thing i can do is lay with the heating pad and hope the pain goes away by the morning(it usually does) i only work 2 days out the week days apart, but as my pregnancy progresses. im getting sore from grocery shopping or if i walk to much but today i didnt do much of anything and it hurts to get up switch positions feels like i went to the gym i dont feel like its normal round ligament pain
