29 weeks pregnant

I am going on 29 weeks in 2 days and I was wondering if the following is normal.

Starting today I have been getting these “twitches” or “spams” bear my lower abdomen right about where my vagina starts. It has been going on consistently for maybe 10 minutes now.. I feel it more when I sit down and don’t feel it as much when I’m standing.

I also have terrible back pain. It happens more when I’ve been doing a lot around the house or something and then my lower back aches SO bad and both of my legs will start to ache and feel sore. I sometimes just feel crampy and gross in my back it hurts so bad I have to sit for a while.

Also at night I have been getting the WORST leg pain. I know it’s normal to get Charlie horses and cramps which I do sometimes but I get more of my legs are aching and sore. I’ll be fine going to sleep and then wake up with my legs hurting SO bad that I have to move them to a different position or get up and try to see if it’ll go away. It hurts to even walk to sometimes it’s so achy.

I also know that round ligament pain is normal, but I’ve been getting sharp shooting pain on my right side for a while now & hurts more or worse when I move into a different position or something. It’s like where your ovaries are and it goes to my side/back a little bit.

I’m sorry if this is a lot I’m a first time mom and I also don’t like to bother my OB if it’s just little things. I obviously talk to him about a lot but it’s also night time and I don’t wanna call for just little things like this
