Does anyone else notice that at times their fingers get red and warm? I know it sounds weird and it is I guess.

I worry that this might hurt the baby. It seems like it happens when I am in a stressful situation (which is alot at my job), am hot, or my nose is really clogged up. All of which are situations that are uncomfortable. Is this normal? is it maybe b/c so much more blood is pumping through my body?
