Sorry if I keep posting over the last few days, but fortunately they aren't duplicates - just getting in one of my really bad phases where everything scares me.

Also sorry if this is TMI, but for the past few days I've been getting yellowy discharge, often quite watery in texture. I've looked it up and Google is saying this is common before a period (I am actually anxiously waiting for a period). I think that I have had it before - it has something to do with small amounts of blood mixing in with the normal discharge. It also said it tends to produce more down there before the period.

Although I think I have definitely had it before, I am still anxious about it as I don't remember it lasting this long before the period or being this much, but then again I wouldn't have paid any attention for it when I wasn't so desperately waiting for my period. I dug a bit further in Google (which, I know, bad idea) and found a source saying it could be a sign of early pregnancy. However, even this source cited oncoming menstruation as the most likely cause.

Is this a worrying thing and has anything experienced something similar? For the record there are no other symptoms such as itchiness or smells so no infection.
