Please Help! Losing Hope

Bree • Been with my fiance for two years. Pregnant with #1!! Due December 2015
My fertile window was 3/28 through 4/4. My SO and I made love everyday, including my highest percentage day. I've been taking prenatal vitamins and cut way back on smoking. My period is due in 9 days. What are my chances that I could be pregnant? (Immediately after ovulation my cervix became very hard, closed and low.) comment please 💘💘💘
