Have any of you felt this way

Autumn
Anyone feel out of breath just walking around? A little background I was born anemic I used to get shots but the doc now has me on 65 mg twice a day along with my prenatal in iron. My bp today 107/70 with a pulse of 103 yep 103!! Anyway I get up to just walk around around the house and I'm out of breath. I'm getting a little concerned about my oxygen carrying capacity and whatnot wondering if any of you ladies are feeling the same way or have felt this way early on. More so in this group because all you lovely ladies are carrying more than one. Still hoping here to see those two heartbeats 🙏
