hi, i am 25 years old woman who is trying to conceive.i had a proper 30 day cycle.in the month of march intentionally delayed my periods for some reason by taking primoult-n.i took a tablet per day for 2 days,i had my period after i stopped the tablet(14th march).then for next month (April) my period got delayed by 45 days.Again in the month of May i had unusual signs of light brown spots for 5 days(14,15,19,20,21).but i dint have periods yet.this is first time am facing brown spots in middle of the cycle.moreover i m sexually active for past 2 months.is this a normal hormonal imbalance ?or should i need to worry about this?
