Think I'm taking a HPT tmrw cross your fingers for me please :)

I will be 20dpo CD38 tmrw..Not my longest cycle but not my shortest. Confirmed ovulation using digital opk and temping..Have had sore boobs for the past week and a half.. keep thinking AF is coming as I've had mild cramps the past 4 days .. Temps have remained high in the mid 98 degrees compared to mid 96 before / at ovulation.. Been waiting as I don't want to take a test get a negative and then Have AF show the next day.. Was going to wait until Sunday but to anxious! Hope this  will be my very first BFP
