So confused

Allison

Alright so hubby and I have sex all the time using pullout method only. We are fine with having a baby just not actively trying but not really preventing. My last normal period was May 21st. My periods range from 28 days to the longest was 70 some days one time. Normally it is between 30 to 40 days. This time like I said my last period was May 21st. Normally my periods are super heavy like my pads are full when i change and i have clotting. This month however on July 7th I had slight blood when i wiped, the rest of the time it was just a lot of brown discharge before you start or as it ends. It was never enough to get on my pad. Onely one time when I wiped was it like my normal period but still never enough to get on the pad. I have taken pregnancy test and all negative. My boobs have been super sore, slightly nauseous, and extra hungry. Anyone had anything similar happen?
