My fiance and I had intercourse on my days of ovulation. My last cycle ended on 8th or 9th of otober. An ovulation calendar showed that i'm fertile through the 14th-16th. It showed that I ovulated on the 17th. My fiance and I had sex on all of these days. What are the chances that I am pregnant? We also have had sex on the weekends. We don't use condoms, and he always leaves it in? My period comes on around the 5th, except last month it came on the 3rd. What do you think I should do? Should I test today or tommorow?
