Leah, sadly it sounds like PUPPPS & I swear it has to be one of the worst things ever. I tried so many things to stop the itching & nothing really worked for long.

Aloe Vera might help a little if you've got some, I had a gel & a spray, I found nothing else helped & I tried absolutely everything as I had it for 8 weeks. Once I had my Dr appointment & said I was going to rip my skin off he suggested I take an antihistamine, so I was on Polaramine for the last 3 weeks of my pregnancy. Apparently the antihistmines that make you drowsy are ok in pregnancy, the new types aren't. The Polarmine was a god send, I used that in combination with the aloe vera gel to get some relief.

Other suggestions would be cool baths with pinetarsal, having your belly out in the sunlight & aqueas menthol (it's a solution the chemist has to make up).

Good luck hun, try not to scratch it only makes the stretch marks bigger & the itch worse.
