Hi. I had my periods last month just like I used to every month. In fact, my periods are weird. It's rarest of rarest scene when I miss. And that is what is happening. I am still not down. Although before my last periods, I had got physical. But I still was lucky to have my timely periods, until this time. Am I expecting? But how is that possible when I had it last month like a normal painful mensurable cycle? Please help. I'm worried as to what is wrong with me. What could be the reason?
