Could I be pregnant?

I was wondering ok so my other calendars say I get my period on the 15th and then my eve calendar said I start in 1 day which I highly doubt but also I have no pms symptoms my boobs don’t hurt which always happens a week before my period but I have been moody and annoyed until get food and I have been having a lot of vaginal discharge like the regular white kind just been a lot though and my boyfriend told me he thinks I’m pregnant and this past weekend we went to six flags I started feeling weird and sick out of nowhere and my boyfriend told me I was pale so I’m wondering when would be the right time to test and is there a possibility I could be pregnant...?
