Skin feeling warm/hot

In currently 16 weeks 1 day and for about the last week I’ve been feeling hotter and my skin has been warm to the touch. It’s normally my face/cheeks, stomach, and breasts that feel warm. I check my temperature with an axillary thermometer like 3 times a day and the hottest it gets is during the middle of the day and its usually only around 98.2-98.6. It’s usually lower in the morning and night around 97.7-98.0. Therefore I don’t believe I have a fever but just wondering if this is normal? Anxious first time mom here freaking out about everything!
