The wait is killing me!😩

So AF is due Saturday (1st September) and my nipples are so sore, dark and erect! (I’ve never had sore boobs or nipples before) Had a little bit of cramping on and off, and had a few days of feeling a little sick(not as though I’m actually going to be sick) also had lots of watery cm for the last 4 days. Done a test yesterday and it was negative but trying to hold out until Saturday to retest. Really hoping I get a bfp, what does everyone think?
