I have worked in the field of Obstetrics and Gynecology for the past 7 years, and have found that these similar symptoms have been the leading symptoms for a condition known as "fibroid tumors". These are generally benign tumors within the uterus that can cause similiar symptoms.
First off I would like to say that it's possible to be pregnant and have your period. Also when your period you do tend to bloat a lot, sometimes it's worse than others. If you have concerns at least call your Doctors office and ask if they think you should come in.
There are several reasons you can look bloated. One, when is the last time you had a bowel movement? You could be constipated, this will leave you feeling bloated and looking a little pudgy as well. The could potentially be pregnant. Early bleeding happens. Test.
