Thanks for the query to ATD for an opinion,
As you are on the 10 day of your cycle, ideally you are in your safe period when ovulation would not have occurred, considering you ovulate by day 14 in a 28-30 days cycle. But there may be a chance of early ovulation, so it is better to take an emergency contraceptive pill like PLAN-B, just to be on a safer side.
I hope i have answered your query,
Wishing you safe sexual practices,
