I had ovualtion ultrasound and doc saw some fluid and i probably would have ovulated already?

one of the follicles measured 21mm during ultrasound. we had sex the night before, same night and after as well. and he also did post coital - took some mucus from inside me and showed me under microscope that lots of live sperm are moving. i usually have 29 day cycle. cycle started on may 31st, ultrasound showed ovulation indication on june 13th morning. wat do u ladies think are my chances of getting preg this month..have been ttc since 11 months !!
