Please tell me I'm not the only one..

I'm 18 weeks pregnant. Last week, we thought I had the flu.. was having weird symptoms like dizziness, very tired, nauseous, etc. But not just like regular pregnancy. Like I felt stuck and couldn't move kind of dizziness then felt like I needed to puke but couldn't move. My husband thinks its low iron and low blood sugar so I will ask at my next appointment. But now, I have a cold!! Runny nose, sore throat, body aches, chills, occasional low grade fever, etc. Like wtf! I haven't been this sick since my daughter was born..
