Is it normal that my baby is like going crazy???

I’m 30 weeks and I’ve been extremely stressed lately. I have bad anxiety and last night i was having bad low back pain and still do but only right low this morning when I walk. My stomach kept tightening and getting hard. Now since I’ve woken up , my baby is kicking me harder then ever before and rolling everywhere non stop it’s making it hard to even sit still because she’s moving so hard and so much. She also feels lower then normal. Is this all normal. I’m used to her moving a lot of kicking hard but this is even crazier than normal
