I am 19 year old female. My period ended on 18th of april. I had sex on 19th of april, the condom get turned at that time my boyfriend don't even ejaculated, for safety he suggested me to take an I pill. On 20th of may I took a home pregnancy test also, it came negative. But I still didn't had my periods. I had an history of irregular periods and used to take iron tablets also due to iron deficiency. Bt from last 2 months I was not taking iron pills as my periods are happening on time. What should I do now?
