Pregnancy Test 😳 HELP

My husband had a vasectomy when our yougest turned 3 Months Old (so about 7 months ago)He had a sperm sample checked he was all good to go, had A zero count... fast forward a few months I had an odd period last month though maybe it was from a cyst it was spotty and light but not to make me think much different until now, I’m three days late .... have taken two tests one was negative then this AM I got this. Anyone had a faint line be a positive ?!?!? I am beyond shocked if this is positive. Anyone else had this happen ?!?!?
