Random bleeding while on the pill?

jessica

Today when I wiped I noticed that I was bleeding and I’m not sure why. I never have this issue while taking my estrogen pills. I I my have sad regularly with 1 person but we ALWAYS use a condom. Wednesday I took my pill about 2 1/2 hours late. Today is Saturday and that’s when I noticed the bleeding. Could this be the cause of the bleeding? I’m kind of nervous.
