dont freak out...stress may cause period mess out...and a lot of reason...

The only way to know would be to take a test. Some women do have a period while they are pregnant, everybody is different and every pregnancy is different. We can't tell you if you are pregnant so just take a test and yo will get your answer.

Just take a test. Probably you're not pregnant since you had a period; it's not terribly common to bleed so much and still have a normal pregnancy. It happens, but it is definitely not the norm.

Hormones in your cycle can cause symptoms like nausea and swollen breasts. Furthermore, you don't immediately gain that much weight on first finding out your pregnant. A lot of women (myself included) actually lose a few pounds in very early pregnancy. But changes in your hormone levels during a normal menstrual cycle can cause you to retain water and your weight can fluctuate by as much as 5 lb., depending on when you weigh yourself and if you've eaten or drunk anything before weighing.
