Has anyone ever tested with swift mainstream tests? I’m due af on Monday but just got two faint positives with these tests, but it has a broken line so I don’t know weather to trust or not?! They came up within 2-3 minutes of doing the tests and got a little darker but didn’t change after 5 mins max, I have been spotting old brown on and off since Monday but seems to have stopped now. I will attach pictures thank you xxx
