TWW HELP PLEASE

So earlier this evening ive had what i believe to be a vvvvfl on a HPT at 9/10dpo..

I have nausea, lower back pain now n then, pinching/cramping pain downstairs now n then, alternation EWCM/Thick white CM.., bloating,mild headache on/off and OMFG my boobs are sore!!!

Could this be a good sign of rainbow baby in the making?
