My period normally comes on the 28th of every month. This month it started around the 26-27th with an extremely light flow, brown ish colored. It's already the 1st and my period has still been a very light flow, like hardly anything is showing on my pad/tampon. The color is either brown or deep red blotches. Kind of like small clumps, it stead of my normal heavy flow that's completely red. I have protected sex, meaning my boyfriend and I use condoms. I don't excersise a whole lot and my schedule is pretty consistent. Am I pregnant? Should I be worried? Please help ASAP. Thank you.
