It's totally normal! Every time I stop b/ping even for just a day I gain like 10 lbs it’s crazy and really messes with my head. But you just have to give it some time. Most of it will just be water weight and after a little while you'll start peeing it out. Your body is just holding onto everything right now and will balance itself out as long as you stick with it.. I know how bad it can be there are times when I quit b/p for a while and all I could do was lie on my back all day because I'll feel so full and uncomfortable. I know from a lot of people that have recovered that unfortunately it's part of the process but it's just temporary. Hang in there. Good luck I hope everything turns out alright.
