White stuff

Next week is when I should take the placebo pill of my birthcontrol and I've had sex but I've been on the pill for almost two months and my boyfriend always wears a condom and pulls out and we've never had one break.  But I've been getting the worst cramps and I'm like super wet but it's white and mucusy.   I don't know what wrong? I haven't started my period yet but it's still a week early.
