I have a viscious case of heartburn that started last night and carried over to this morning. I thought it was due to my homemade lasagna last night, but when I woke up and got heartburn again within 30 minutes, I knew it wasn't just lasagna. Perhaps its hormones or something baby related. In pregnancy, everything can be attributed to being pregnant. I'm 24 weeks along, have gained 20 pounds and, aside from heartburn, feel fine most of the time. Sometime I feel some pressure way low in the belly, either because baby is stretching or because... uh, I really don't know why.
