Eh, yang rasa panas tu boleh jadi normal actually, hormones pregnancy memang boleh buat sensation macam tu, tapi sebaiknya check with your doctor je untuk sure, especially since you're still in the early weeks. A few of my mum friends experienced random heat sensations early on, tapi better safe than sorry when you're pregnant, so mention it at your next checkup! Takut-takut ada something else, so it's good to get it checked out properly. Congrats on the pregnancy, by the way!
