Okay, so I'm 25 and I've had a regular period since I was 13. They happen normally and last 7 days and are always pretty heavy. Though last month was the first time it's been weird and was pretty light for about 5 days with none of the usual cramping/headache/ mood swings/etc. Then 4 days ago about 3 days prior to when my period should start I have some very light pink that I saw on the toilet paper for about 2 days and then I've had nothing since then and it's about that time for my period to start but still nothing. I wasn't sure if I could be pregnant or if it might be something else. Again no cramps or mood swings though I have been a little bit nauseous. Just not sure if I should be looking to go for a test or to the doctor for something else.
