Women do not have a real period when they are pregnant, they are simply having bleeding which resembles a period..

You could theoretically be pregnant, especially if you were not using protection!

A pregnancy test should be accurate during the week you have your period! Pms and preg symptoms are similar, so it can cause paranoia..If you are worried you should get a blood test.

Thank you so much for the info.....So even if I am having bleeding when i'm supposed to start even though the bleeding is lighter and is shorter it won't affect the test if I take while I am bleeding or should I wait until I quit bleeding? My period should start around the 13th of this month......Last month it was 3 days early and only lasted 4 days(it usually lasts 7-9 days)and the month before I was 3 days late and it only lasted 5 days.....And it was really light(only one moderate day both months, and the rest of the days was more like spotting when I pee). My boobs hurt, i'm sick just about every morning, my lower back hurts, i'm very fatigued, having more headaches than usual, I feel flutters in my stomach...And I know its not just gas....But i've head that after having an iud removed you could feel flutters....I guess kind of like muscle spasms from having the iud, my stomach is getting big....But i'm not gaining weight or losing weight....I have 3 kids and with my last one I actually lost weight before I gained any with her......I'm just really confused about it now....But thanks so much for the info...... :)
