Bloated stomach and getting bigger though I eat 3x a day small meals.

No short answer. You don't mention pain, nausea, vomiting or constipation. There all a lot of different "small meals". If it contains several rolls, or dips of ice cream you may be getting too many calories, or not exercising. I trust you have done a pregnancy test. I have noticed that 45-50 yrs old is a time that women have more trouble with weight. You should see a physician as there are other possibilities.
