Period or Pregnancy

Hi I really need some opinions right now. My last period starts May 4 2015 and I have a regular period. It lasted about 5 days. My partner and I have unprotected sex days after my period. We've done the pull out method.This happened twice. This 2nd week of June I've got this yeast infection for the first time. During the said infection, I spotted a very very light bleeding just for two days.Maybe it is caused by the infection. The infection lasted about 1 week and 2days. After I recovered from the infection , it is the due date for my next period to start but it never came. I was a week late already when suddenly got light cramps last June 20, I also got a headache the next morning but doesn't last. In that week, I feel changes in my body, I feel bloated, craving for salty food, feeling uncomfortable especially at bedtimes. I sometimes feel I was about to throw up but not really often. I also feel more hungrier and thirsty than usual. I feel I need to pee every midnight or early in the morning which disturbs me from being asleep. I feel also my breasts became fuller and a bit painful to touch.I never done any Pregnancy test yet. But this June 25 I got unusual bleeding. This bleeding was light and on and off. It is brownish red. Sometimes it is red like fresh blood but turns to brown again. I was thinking maybe it is my period because Iam currently for 7 days now. But it's just weird. It is a very light to medium bleeding and can't even full any pads just for 1 day. Sometimes I have light crampings just for a minute during the bleeding. Now I am still waiting for when this bleeding stops. Is this bleeding possibly be my period?
