Cervix dischargeI'm so confused... .. .

I'm actually really confused. On November I had my period on the 25 and lasted for 8 days. On Wednesday I was 21.7 percent to get pregnant. I didn't know I was on my fertile window until the next day to log my info. I've been lately so really wet down stairs and tomorrow im suppose to get my period. I've been nauseated/vomiting, back lower pain and mostly every day I have headaches and soft cramps that goes and comes. Why am I still wet down stairs, is it normal?? Or could I be pregnant??? Or just wait until my period its not here at all???? ( I just need advice please this is the first time it happens been wet down stairs).
