Started the pill 6 days late, pregnant?

Hey everyone,
I have a question for you all... I started my pill (Deso 20) 6 days late, and my partner and I have had unprotected sex several times, both during the time I was supposed to get my period and after it until now. For the past few days, I've been experiencing dizziness, my head feels like I'm on a carousel. I also have headaches, irritability, crying for no reason, cramps, and nausea, sometimes in the morning, sometimes throughout the day or even in the evening... I'm trying not to overthink it, but I can't help but think about it a lot... Could I possibly be pregnant now? I've been taking the pill since I was 14, and I'm now 22... My partner and I really want a baby and have decided to go for it after this (school) year, since I'm starting adult education in September and learning a new profession. I'd prefer to finish school and find work first. That doesn't mean a little one wouldn't be welcome in our warm family! What do you think? Many greetings, Lies
