pregnancy constipation?

I am 25 weeks and totally constipated. I've had history of constipation. I go a little but not enough for what I eat. I feel bloated and it hurts. Past days, I've eat more liquids (soups), oats, etc. But only little luck. I don't feel like I have to go but my abdominal area feels like it needs to. I moved so my appointment with my new doctor is in 2 weeks. I've tried all natual vegetable stool softners, metamucil, etc. I need to feel better
