Advice?

Kucera
Maybe this isnt supposed to be asked here , but i dont know where else i could ask. Okay , so af was due on the 12th , but it came on the 11th , or so i thought.. it was light spotting , then got a little heavier by the 12th. By the 13th it was light again, and now it stopped. For me af usually lasts exactly 7 days , and is really heavy. But this was way shorter and different. My husband and i decided to take a break for this cycle , but is it possible that i might need to go pick up a test anyway? Please be nice..
