BC but symptoms...

Okay, I've been on bc for 3 and a half years, since after the birth of my son. I take it everyday but lately I've been falling asleep before taking it so I take it the next day as soon as I wake up. I skipped the sugar pills last month and jumped right into the next pack because of an anniversary trip we were taking. I would have started the 13th, but started my new pack the 9th. Now, I usually start the Thursday of my sugar pill week, which would be the 4th of December. We sex three times during what it says is my fertile week, and now I am freaking out. I've had one child already, so I'm a little more sensitive to the sumptoms of early pregnancy. I know I'm probably freaking myself out and it's probably just because I missed a month, but I've got symptoms like my first pregnancy. The symptoms I got around  this time in my cycle last pregnancy were sore breasts, a small cramp followed by a small pink spotting then just stopped, and the 'feeling' of being pregnant. Now I know this doesn't mean I'm pregnant, but I just needed to vent and get advice or input from other ladies on bc. Thanks in advance!
