Actually my friend she has thyroid she was having irregular periods which means she had periods thrice in two months. Which might be because of intake of ipill continuously. This month she had sex on 4 where the sperms did not went inside her and had her periods on 9 which was her actual date of periods for this mnth. She had periods in a very little amount. Like we girls have on our 7th day she had that little amount of periods in the whole span of seven days. Not even a single sanitary napkin was fully consumed. Nor she had any ipill this month. Is there any chances of pregnancy. Or is it because of the heavy flow of blood in those last two months of her period which has lead to little amount of flow this month.
