Worried!!!

So I just took my blood pressure to log it. And it was 110/70 but my heart rate was 144. Now idk if that's too high. But I have a thing for having a really high resting heart rate. And I went a took a nice warm shower with lavender Johnson Johnson soap. In the middle of the shower I got really light-headed. Now I'm lightheaded and my breathing is very laboured. Like is terrible and I'm starting to feel really fuzzy, if that's the word I could use. I feel very out of words or confused sort of. And it's killing me. I'm 34 weeks btw please help I'm worried about my baby girl.
