I just wanted to post to say that on the day AF was due I took a One step internet cheapie test which was stark white! No second line even when tweaked. But something didn’t feel right so I took a first response later that day which was a very obvious positive. I just wanted to say if you do get a negative on those don’t get disheartened, definitely try a different test! I was not expecting a positive on the first response after seeing a stark white on the one step! Top is 12dpo bottom is 13dpo with first response rapid result.
