My period date is 26 the of every month since long time. My age is 23. I had may first sex with my BF on 6th this month. He ejaculate sperm outside but for precaution I take IPILL. Next day I feel some headache and Vertigo. From then all is fine. But on 23rd I start bleeding (3 days early from regular date 26th of period) and it comes in very little amount like last day of period and it comes for only 2 days and than stops. Already 4 days passed than regular period date 26th. Is any problem? Do I have to consult the doctor for pregnancy check ?
