Two week wait symptoms

We've been trying for several months for #2, still breastfeeding #1 (11 months) but weening her. The past few nights I've had night sweats on my chest and neck, and once or twice a day I'll get a short but splitting headache. Period was due today but I tested positive instead 😊😍😊 (overjoyed of course). I'd just like to know if anyone else experienced night sweats while hormone levels increased in very early pregnancy?
