what should I do?

I've been distracting myself to keep my mind clear of texting my boyfriend. We only been together for 2 weeks . Here is the thing my boyfriend never hit me up even when we started off as friends that often. He hits me up like every 2 days, I don't bother him or text him unless he texts me first. We aren't fighting or anything he was suppose to come over the passed 2 nights but he never came. Today I haven't heard from him all day but he has been active on facebook. Yes, I have been checking if he is active I have trust issues but I always make sure I give him his space. I don't want to come off as clingy or needy even though I know I am low key lol. I never show it , what should I do ? Am I over thinking it ? I really like him and I don't want to mess up things.

edit : he doesn't text me every two days he normally texts me every day he text me last night but haven't heard from him he was the same when we were friends. I don't wanna come off as clingy , I really really like this guy but I don't wanna bug .I could possibly be pregnant too . We started off as friends then got together.I can't take a pregnancy test its only been 11days and I missed my period so far.
