16dpo, need advice please

Julia
Hello everyone! I have an average 30 day cycle and am currently on CD 34/35 (I think). I'm 16dpo (used the clear blue digital to determine ovulation and also CM). I took a FR HPT last night and it was straight up negative. I'm usually regular 30 days, give or take 1 or 2 days. Usually when I don't want my period to arrive, she takes it upon herself to show up early. I've got increased cm over the last few days and have sore and heavy boobies, also extremely tired even though I've been getting a bit of sleep. I bet you after I post this AF will arrive! I'm just wondering if anyone is experiencing something similar and whether I should just keep peeing on the sticks until AF shows (if she does) or go to the doc.
