Hi I am 26 years unmarried girl, I missed my periods last month, my last period date was 13-02-2016. After that I had intercourse on 15th and consumed ipill and again on 19 and 20th I got period for two days. I got checked myself with pregnancy test card and blood test for pregnancy from lal path lab. But both tests were negative means I am not pregnant. Then I consumed 10 tablets regestrone 5mg tablets for three days (three tablets in a day) on 11, 12, 13 april 2016 and one on 14th april 2016. But till date no periods. Kindly suggest me on this. An early reply will help me to get out of stress. Thanks in advance.
