My cycle comes on different days of the month, it does not come the same date every month. I was wondering if its a possiblity that I could be pregnant because I have been feeling sick to the stomach, going to the bathroom a lot, having cramps in my stomach and brest tenderness.

The funny thing about this situation that confusses me is that every month that I have my cycle my breast are tender and I sometimes throw up. (I guess depending on the side where the egg comes from)
