I am trying to conceive but my utra sound reports say there was no follicles shown while it was done on 14th day of my periods cycle. My periods cycle is 28 to 32 days and they are never late but once in the month of june it was 6 days late then I got my periods now I have missed my period of september and still missing till it is October 18th , the strip test is negative. I went to Dr. She gave me some blood tests and gave myfol tablet and duphaston she said if there will be a baby it will protect it but if there is nothing then my periods will come so I want to ask you how many days would it be taken by these tablets to get back periods because I am still having no periods and delayed my tests due to some reason . I am very confused to know that instead of having myfol tablet for five days my periods did not come yet ? Is it because of pregnancy ?
