Need someone to talk to!!

Kimberley
Hi all.. Right I'm just going to cut to the chase.
I'm on the combined pill (Yasmin) I have been since I came off my implanon in July which I was on for around 7 years now here is my problem.
I went into my 7 day break on 5/02/16 and didn't have my bleed. I haven't taken it yet as I still haven't had my bleed I'm usually due on the 16th but I have had nothing and no symptoms of starting and usually I am like clockwork since I came off the implanon. 
Could I be pregnant? I'm always hungry, my mood swings are everywhere and I hiccup and belch for no reason and sometimes I either get a pain in my left breast and other times both of my nipples tingle and feel like someone is playin with them lol (to much info).
What do you think this could be? Should I wait a little longer to see if I bleed?? 
Please someone help me I'm nervous as hell :/
