As you mentioned that you had unprotected sex for two days and on third day you had your menstrual cycle, which was lesser in flow as compared to your previous cycles. Also, you had Posting during your period as well and also during your previous period as well which were normal.However, you should be assured that reduced flow during this period doesn't means that you are pregnant. For pregnancy to happen, ejaculation needs to happen before or during ovulation, which occurs during 14th day of cycle. However, as you had your periods after as well hence, there were no ova available for fertilization. Spotting or reduced flow during menstrual cycle can be due to anemic state which might have been persisting due to excessive blow flow during previous period which might have been resulted due to posting which you have taken.Hence, I would advise you to consult a gynecologist for reduced menstrual flow which might have resulted from anemic states, which might require treatment as well. Thank you. </s>
