Pregnant!??? Updated

Hey y’all!! I’m 16 and scared. Me and my boyfriend just celebrated his 17th birthday by obviously have sex. It wasn’t our first time or anything. But I’m on birth control and he pulls out. I missed one day on my pill the day after our celebration. And now I’m late. I’ve been late before but only by a day but I’ve always gotten my period and I’ve yet to get it. We didn’t use a condom so I know there’s a chance pre cum could have done it. I just wanted other opinions on if I should or shouldn’t start to freak out.

UPDATE::

I still haven’t gotten my full period but yesterday for about an hour I had extremely light spotting. It was kinda pinkish red but didn’t last long at all. But I haven’t had anything like that today. Is that implantation? I’m going tonight To get a test to take tomorrow morning. But I just didn’t know if the spotting was implantation.
