11 Weeks today and breathing issues??

I'm 11 weeks today and I'm JW if anyone else has had the issue of having a hard time breathing that early on. I've heard if it's a girl they take more out of you and this baby is literally taking everything out of me including my breath. I'm use to working in a hospital 12 hour shifts and have never had an issue I no longer work there now but my body is use to constantly going and close to 2 weeks now I've noticed I can hardly accomplish anything without having to sit down a dozen times. Something as simple as tonight I was making dinner Browning hamburger and had to sit down twice because I get weak and my chest is like it's hard to breath and I'm having to take deep breaths and my heart feels like it's racing but I check my pulse and it's normal and I will feel it in my abdomen as this is going on, walking in Walmart to get a few groceries is a chore now literally after maybe 15 minutes I'm leaning on the cart and having to sit as I feel my self get weak and I feel myself go pale and again all the same symptoms and I'll feel it in my abdomen as well I'm 117lbs and never have had an issue health wise like this before so to feel it is concerning. Any of you ladies have or had this issue?
