I've been taking Ortho Tricyclen Lo for a while now, about a year and a half. A couple weeks ago I forgot to take the first light blue pill (day 7 i think). I remembered it the morning after, so I took it right then. So then about 10 hours later I took the next light blue pill as regularly scheduled, and continued with the pack normally. Well I was supposed to get my period on Wednesday, two days ago, it is now Friday (and I am on my 6th dark green pill- only have one more left until I start a new pack). I did have protected (condom) sex once during this 28 day pack. I haven't gotten my period yet and I'm wondering what to do or what could be wrong? I am feeling a little crampy, etc. just no bleeding yet, so as you can probably tell, I'm very worried. Please let me know! Thanks!
