I am 22 virgin. I had my last periods on 6th of march 2014. On 24th of march me and my boyfriend were having fun at my home. While rubbing his penis on my vagina he came.. but he immediately changed the position and came on my stomach.. not very sure That it did touched my vagina or not (sperm). Any ways from past few weeks I am going through fatigue.. I can not get up from my bed. I have my regular periods of 28 days cycle but this time it is a week late and still no sign. I feel like i am about to have it but its just the while fluid. And from past 3 days only a pinkish discharge in the morning.. i am feeling stressed out. Having headache and sleeping too much. What can the possible reasons be for missing the periods?
