Hi, My period was regular earlier ie., before we think about having a baby. 28 days cycle. On May 2019 I missed my period and it came after 47 days took duphston tablets for this. And next period came after 20 days only then after that it was regular. Now my period suppose to come on 21st of September but It has not come yet , took a
pregnancy test and it is negative... What can be the cause why it is like this... please help me to find the solution
