Could I be pregnant ...

I’ve been trying for 3 months, but this time I really feel it worked. I’ve been getting head aches ( which I never get),sharp shooting back pain ,feeling nausea, increase in urination, cramps, my boobs look full sometimes hurt then feel fine and now butterflies like tummy tingling. Some days I feel normal like it could all be in my head the tinging is something I’ve never felt before.I took a test 9 days before my period (in the morning) and got a faint positive. Took one 7 days before in the afternoon it was negative I start my period in 4 days not sure if I should just wait or take another one in the morning
