late period but on the pill

Ivy
I've been on the combination pill for 6 months now and I've always gotten my period on the second sugar pill at around 10-12am.  It's now 1:41pm. I have been stressed about getting it for the past few days, even though I take my pills at the exact time every day. My boyfriend and I have sex once or twice a week and he always pulls out. Has this happened to anyone else?
