Feel like I’m pregnant with twins?

My doctor called and told me my blood test showed very high levels of hcg for being so early (3w4d) and I just feel like I’m having twins. I can’t get the idea out of my head, and I had a dream about it last night! I’m terrified at the idea, so I’m secretly hoping I’m wrong. Also I’m a little bloated but feel like I’m starting to show (based on the top of my stomach). This is my second pregnancy so maybe my stomach is just looser. Anyone else had this feeling before? Were you right? Here’s a pic of my “bump,” I’m a pretty active weightlifter and cyclist so my abs are usually much tighter!
