OK so my period this month was a week late and I'm usually pretty regular with my period. I think I got my period but it only lasted for 4 days instead of the usual 5 days and was heavy for the first 2 days. But I have experienced severe headaches and cramping before and after I got my period, and I noticed that I'm eating a little bit more. I have heard of people getting their period while they are pregnant do you think I might be pregnant? All answers would be helpful.

You wouldn't technically have a period if you were pregnant. You can have some bleeding however.

This sounds more like just an off period than pregnancy related. That it was a bit later than usual, may account for the heavier flow to start. Many of the symptoms a woman might feel in early pregnancy are also felt around the time of a period.

If you want to be sure, you could always try a pregnancy test.
