False positive not that common. I agree with trying with clearblue. Wait another day or two and pee on the pregnancy kit first thing in the morning.
Get those slightly exp but v sensitive type thats spells out pregnant/not pregnant
Try Clearblue digital. It will tell whether pregnant and roughly how many weeks.
I think you must visit a doctor and get tested professionally
Hi, Wait for couple of more days and the try again
Maybe you can try testing it another morning?
Try multiple different brand to double check!
