Iam 22yrs old. I used to get my periods regularly for every 28days. Last month I got my period on 23-08-2018 and I was expecting to get my next period on 21-09-2018. But, on 23-09 I saw a little bleeding only for that day.
I have taken a pregnancy test and it was negative. Doctor suggested me to use deviry tab from 09-10-2018. What does it mean? Can I still be pregnant?
