Hi mata! Since you ovulated on march 29th and you're now 15 days past ovulation, I would think you should expect your period within the next two days. It is very unusual to have a luteal phase (from ovulation until your period) of more than 16 days. Sorry about the negative HPT :-(
took a home pregnancy test today, it was negative...15 days after ovulation and still no period....I want to know how many days my cycle is??
