Constipation? Something else?

I have been super constipated for about 2 weeks now. Last week I called my dr office because I thought I had UTI because of severe back pain but they thought it was related to constipation (it had been about a week of nothing). So they put me on a crazy regimen of stool softener 3times/daily, brown bomb 2times/daily and miralax 2times/daily. I have gone about every other day since starting this regimen but still have severe back pain.

I went to walk in clinic this morning because I wanted to rule out a UTI ( I had blurry urine yesterday). They confirmed no UTI so now I just feel defeated. I am 24 weeks today. I need some relieve from this pain. 😔 I have only gained 7 lbs so I don’t think the pain is related to that.

Thanks for any advice.
