Nervous/ should I be??

Lauren

So I am on the 4th day of my placebo week, Wednesday. I usually get my period between Monday-Friday but my fiancé and I had sex and he came in me on the last day of my fertility week. I take my pill religiously at the same time every day. I highly doubt I could be pregnant, but waiting for my period to come this week is nerve wrecking. Any advice would be appreciated!!!!
