I am on the pill and I skipped a period because of a vacation and I've been taking the new set of pills for 5 days now and last night I started having terrible pain in my stomach and so I thought I had to use the restroom when I went to the restroom I found what looked like blood clots some were really dark purple some were kind of off white some were black and some were pink. What's going on?

whitley10, go see your doctor and voice your concern. Clots form when blood sits there and doesn't come out right away. Your next period could be normal and this was a one time thing because of the missed period. Changing to a different pill can affect your body too.
