I think my preggy belly just gradually overtook my bloated belly, ITMS
The bloating does suck though and I was always a lot worse in the evening (and I am again). I take a fibre aid (like Fiber Gel) every day which does help and try to eat smaller meals, especially in the evenings. I found I couldn't eat as much as the weeks went by anyway so that may explain while the bloating subsided

I had tightenings more so than cramps after the first tri. You do get growing pains the whole way through though (round ligament pains, tight belly, stretching, etc) so try not to worry
