Having white, watery, discharge for the past few days and it's been extremely heavy!

I'm sorry if this had been asked before, but the past couple days I have had an excessive amount of white, creamy, watery discharge. Is this normal? I've been TTC for around 6 months now and this is definitely different then any discharge that I have noticed. It doesn't itch, doesn't smell, it's just heavy and has me wondering if it's normal, abnormal, or I don't wanna jinx myself, possibly a sign of early pregnancy.....? Please give me some advice!! Also, last time my fiancé and i did anything was on my peak fertile day and i used pre-seed. I'm about 3DPO. Thank you!! ~Katy
