I have been on Ortho tri cycles lot for about 3 years now and last weekend, my boyfriend and I went to Vegas for the weekend. I took my pill on time on Friday, but forgot to take it Saturday and didn't take it until 12noon on Sunday. I took my Sunday pill 4 hours later at the normal time I am supposed to take it. On Monday, I forgot (once again) to take it on time and didn't take it until 10pm Monday night. I woke up on Tuesday morning with spotting and now have what seems to be my period. I have had times in the past where I take my pill late like this and have not experienced early periods. Any help appreciate!
