I'm on the pill, take it perfectly. my period is on time too but it is red brown slimy. and it is much lighter than normal. preg or something else?

Not likely pregnant: Check a HPT if you are concerned,, but not likely pregnant. Even with OCP you may see some variation in the character of the flow. "Brownish " tends to be old blood vs the bright red that may show at the end of the flow. It is also possible to skip a withdrawal bleed on the pill if you are stressed. Continue to take the pill at the same time every day and use condoms for additional protection
