You know what I'm wondering the same thing that you are. I had a cycle on the 30th of june and it was not as heavy as normal, but heavy enough to use a tampon. Then on the 16 of august I had really light bleeding (spotting) then it got a little heavier (staining), I asked my doctor during the physical why am I having two cycles and he told me that he wants to get a pregnancy test done, unfourtanatly I had used the rest room already so now I have to wait to go to the lab and get blood work done. Since it's not until later I don't know what to think. I just wnat to know if I am or not, it's strnage for me to have 2 cycles that close together.
