I am almost 4 days late for my period. The latest I've ever been (abnormally) was 2 or 3 days. I normally start on the exact day I am supposed to or a day late. Today around 4:00 PM when I used the restroom, after wiping there was a very light pinkish color mixed with a small amount of clearish discharge on the paper so I put a pantie liner on... around 7:00 PM before my night class I went to use the restroom again and there was nothing on the pantie liner but again when I wiped there was the pink color again so I put a tampon (light sized) in during my class I started getting really bad cramps so I though for sure this was my period about 2 hours later at around 10:30 before getting in the shower expecting to see blood on the tampon after taking it out there was barley anything on it just a very small amount of a light pink/ light brown at the tip. Just before sending this in I went to used the rest room again and when I wiped there was nothing at all. Can you tell me what I am experiencing, could I possibly be pregnant?

It sounds like you're having an off period, but pregnancy is definitely also a possibility.

Wait until your period is at least 2 weeks late, then test using first morning urine.
