Postpartum sex pain

So, I'm concerned. I've been having pain deep in my abdomen area it's a constant pain and not a crampy feeling more like a dull ache and this has been going on for or a few days I have a yeast infection right now I'm not sure if that can cause this feeling and I haven't had sex since finding out about the yeast infection

I am taking a UTI medication that I had left over just Incase it's not but ive had yeast infections before so I know what to look out for. I've never experienced something like this sorry for going into detail but I'm hurting and can't get into my ob for a bit
