Tummy when pregnant?

Just wondering if anyone could tell me what their belly felt like whilst they were pregnant? I've recently put on weight (to my tummy) but I was always able to suck it in well but I can't atm. I do suffer from dietary issues but it's been a while... I've had had tender breasts and other signs. I have had unprotected sex in the last few weeks but I also have had a period in 2 years because of the pill (the one that stops me ovulating). But yeah my main questions is what did your belly feel like?
