Hi. My last period started on the 5th of august and I had unprotected sex on the 12th of which I still had drops of my period and then 14th again when I had no period drops. I took postinor 2 on the 15th like 10hours after last sex. My period came out again on the 19th of August and then flowed normal but I think I can see some brownish smelly discharge which has been till date after the period. What might be the cause please? A quick response will help me I beg. Thank you
