Period Question, or maybe it's something else....?

I'm 20 and about once or twice a week I will have this strange substance come out of my vagina, it very well could be discharge i just that I don't feel anything till like my underwear feels wet, almost like I peed myself, or maybe if I just started my period, I would go check and it would be like water, no color, no smell, no thickness to it, my underwear just look wet. And if I'm at work I'm pretty much stuck with it till I get home and when I go to change them, it's dry and my underwear are like an off white and crusty, gross I know, my discharge is usually thick and white and this has been happening for oh, I dunno like 5 months, I still regularly have the other discharge, and I am sexually active, and I do my have my periods on time, and they have been regular, and I'm due to start here in the next day or two and it just happened to me again today.. I just want to know if it's something I should worry about, or if its just discharge or something to do with my periods, please help

I get that all the time. As long as it doesn't smell or turn to a wierd color you should be ok. Ask your doctor next time you go in just for peace of mind.
