Well me and my boyfriend had sex, and we didn't a comdom, but the next day I started my period, but I have all of the symptoms,and so does my partner what does this mean.

Typically it means you are not pregnant. You have to have sex during or immediately right around your ovulation time to get pregnant.

If you have a typical 28 day cycle, your ovulation period would be around 12 - 14 days after the first day of your period.
