I'm so unsure

Laura
So I'm cycle day 40 and than never gone past 31 but normally I have 28 day cycles. All pee test negative and so was a blood test last week. But I still have not started. I'm extremely moody, my nipples itch and I have a ton off clear/creamy discharge for over a week. Could the blood test be wrong? My husband and I have had multiple unprotected even on the day glow predicted for me to be most fertile. Could I be prego or just really off balance hormonaly.
