I am sayani pal, 22 years old marriage woman. My expected date of period was 10 th december, but I had a prolonged protected sex with my husband on that 10 the november, till now I had not get my period. Till november I had my regular period. Till october I had normal flow. But in november I had very heavy flow though it was completed around the 5th day. I had to travel around 60 kms/day, four days in a week, I had shifted recently, before shifting I usually had a healthy diet, but now I can take much healthy diet, like no milk, no eggs, no dates, nuts etc. After having my period on november, I had not sex for a month. And had the sex only on 10 the december, my husband and me both are sure that there was no leakage in condoms, then why I had not get my period yet?
