Ugh help

I don't know what's going on with me..

I have two boys ..an almost three year old and my youngest just turned one on the seventh

I have also been pregnancy other times and he miscarriages early on

But with this pregnancy it's different

I get out of breath.. when walking or laying down.. mostly walking.. not fast.

My heart rate is 105 when resting...

my blood pressure was 133/80 tonight when I walked around for less then 5 minutes first..

I get winded when bending over..

I am constantly cold.. or super hot.

My other pregnancies were not like this.. until the end. My blood pressure was up toward the end of both but was 120/70 until around 32 weeks with my boys

I AM ONLY 5 weeks and a few days pregnant..

Haven't been to the doctor yet but I am starting to worry.
