I have been on birth control for a little over a year. I have taken them perfectly up until recently. I started my new pack three weeks ago on Tuesday. I take them at 8 p.m. I missed Wednesday's pill, but took it Thursday morning around 8:30. My husband and I went out Thursday night, so I missed Thursday nights pill. I took it Friday morning around 9 a.m., and I took Friday's pill on time. I also took Saturday and Sunday's pill right on time. We had unprotected sex on Sunday, and I have taken my pills perfectly every day since. I never really thought much about it, but now have started to worry. What are my chances of being pregnant? I've had no spotting or other pregnancy symptoms, but I am so nervous and upset.
