Hi, I've Been On The Ginette 35 Contraceptive Pill For

Hi, I've been on the ginette 35 contraceptive pill for 10 months now . I had finished my previous pack and hadn't got a new pack until 2 days later , so my next pack started late....I took the pills like I usually do and there were no side effects but now my period is 2 days late and I'm not sure if it's because I started the last pack late.
