I am on the pill and have skipped 4-5 periods while on the pill is this bad? My period is due next week but i have started lighty bleeding that is like a browny colour this week and has been goin for about 2 days now? Wat is this and is it due to skipping periods or different reason? the only other reason is because i have been taking some pills late due to sleeping in but have still not missed a pill ever. also am i protected still?
