Hi @Mgeno4bny! I also am due AF 1st December and I am 10DPO.
So to start with - 3dpo you definitely wouldn't have implanted yet (this is normally 6dpo - 12dpo) so any cramping and bloating then is more than likely other causes.
5dpo a sharp pain in your side is a little early for implantation, but could be - so that might be a positive sign!
Now at 9dpo bloating and light cramping is a good sign that there is plenty of progesterone - this causes wind, bloating, and other such digestive issues. Nipple soreness is good too if that is unusual for you - have you noticed any darkening, or veins noticeable?
My symptoms so far have been sore boobs and hot/sore nipples, metallic taste, tiny amount of pink CM yesterday, light cramping, and backache. I haven't tested at all yet and am going to wait until Monday to test I think, after AF is due. Saves money and frustration on potential false negatives. If you can hold out as long as you possibly can to test that's great, though if you want to try a FRER you may see a result from today onwards - it's still very early though. Ideally you want to be 13dpo+ before testing but that's easier said than done!
There's a great website here Countdown To Pregnancy that shows it's still a less than 50% chance of getting a BFP 9DPO. Even at 15DPO theres still a 6.4% chance of a false negative so the longer, the better
good luck and baby dust to you!
