A Jencyclen slip, I'm afraid I might be pregnant!

Julie
I've been taking Jencyclen since Jan 1 after coming off the depo. I had taken the pill everyday at the same time every day without fail. Well, last month I had a normal period and I happened to run out of the pill that weekend while we were out of state and when we got back from our trip I completely forgot to go get a refill after 3days. Problem was I didn't have the money for a refill until my next payday so I was without birth control for a week. We had sex within the week maybe 3 times, but I figured what could be the harm considering it took us 8mo to conceive our now 9 1/2mo. So I decided to wait until my next period to start my new round of birth control thinking it would come within a few days of not taking the pill. Problem now it's been a month and I still haven't started my period and I'm freaking out! I've had symptoms like I was going to start my period like slight bloating, back aches, migraines, slight nausea due to the migraines, and cramping, but no period, no bleeding. What are the odds of getting pregnant right after coming down from a birth control like Jencyclen??
