Hi, Since past one year my periods are quite regular and have a 30 days cycle. I last had my periods on 6 March. I took HPT on 33rd and 39th day of cycle which turned out negative. I took regestrone 5 mg thrice a day for three days from 40th day of my cycle. On 48th day my periods started but it was brownish in color and light and lasted for only two days. I am not having any pregnancy symptoms. Is pregnancy still possible? If not, then what could be the cause of delayed and light periods only for two days?
