Should I take plan B?

Hi everyone!

I know this might sound weird but I am a person with lots of anxiety when it comes to thinking I’m pregnant, even with just like a fingering by my boyfriend. Lol! I know I’m so weird! However that being said my boyfriend and I have been together for almost 4 years and we did decide to finally have sex! But not in a normal way. I didn’t let him fully penetrate me and he was wearing a condom he also didn’t. Ejaculate inside of my with the condom. He pulled out and finished in the condom. It was very enjoyable but I am now worried that I might need to take a plan B since I’m kinda close to ovulation but I also feel like I’m over reacting a little bit. I would love some tips and help on what I should do because I’m freaking out!!!
