miserable constipation please help me ..

I tried everything in these past 2/3 days. Prunes, water, lemon water, cereal, oat meal, eating a lot, eating less, dry cereal, apple juice, massage, walking around .. nothing’s worked. Please someone help I’m so uncomfortable and miserable, I feel pain because I’m so full and bloated from trying everything but when I push so much only tiny little pebbles come out tmi I’m sorry but someone please help and I don’t want to try any of the liquid powder laxatives bc I know they’ll make me puke.. and apparently none of the pill forms are safe for pregnancy .. please someone help with advice.
