What?? (tmi post)

So I’m 31 weeks I’ve been to L&D 2 times for contractions this past month and they had to give me shots to stop them. So last night I started having them again but only 2 an hour and I woke up this morning I had to poop and it was stuck half out for 20 minutes. After it came out I started to have contractions every 15 minutes and now I’m having them and when I have them a bit of poop comes out and I feel super sharp pains in my lower back should I call ob? Or try to go again and see if it stops? I’m kinda freaked out by this and I’m embarrassed to call the doctor. BTW last visit was Monday and she was head down and started to drop .
