I am 33+2 weeks pregnant.. I haven't had any trouble with pooping until now..

So I was out with my husband I then realized I need to make a BM.. went to the toilet and pushed it began to come out and then it got stuck like I couldn't push it out it was like a rock.. I couldn't get it out i was In the toilet for at least 20 minutes and every time I would push hard I would wee a little bit.. I'd lean over and stand and walk... I could not get it out.. eventually I just had to suck it back in and cry to my husband who was worried sick about me.. I couldn't still on my bottom cause I could feel it there.. 10 minutes late the poop feeling came back.. I went to the toilet and success it came out but with some cramps and it was like pebbles!!

My question is can this effect my baby in any way.. especially from sucking it back in..

I'm so traumatized and worried about my baby.. Thank you for reading my horrible poop and it's grossness.
