I’m just being crazy, right?

So, it’s weird. Idk lately I’ve been super sensitive to caffeine or like vitamin B or energy shots lately. It’s making my arms go almost numb. I can use them just fine, I have a pretty physical job, but they’re numb or almost numb. It’s only when I put any kind of energy thing into my body though but it’s only been going on for like a few weeks. Now, I know for some women (probably me, with my luck) pregnancy increases your heart rate, even early on. My husband and I had sex literally 2 days before my last period. There’s no way this could be a pregnancy thing, right? Like that’s not possible, right? My body just hasn’t been this sensitive to stimulants since I first started drinking coffee as a young teen. I’m just being neurotic and crazy right now, right? I feel crazy just posting this. That has to be it. Right?
