When's your period due OP? My only thoughts are that 10 mins is too long for most tests and any results after 3 minutes aren't valid. Also I'm pretty sure getting milk at this stage wouldn't be typical... unless you've got another small baby already? If you're testing early I'd wait- I know it's really hard but honest to god it's not worth spending money on loads of tests when you're much more likely to get an accurate result after your period is due. Fingers crossed for you xx
It seems pretty unlikely that they would all be evaps, particularly as it looks like you have used more than one brand of test. Are the lines still there now or have they faded? I always found that evaps disappeared after about 12 hours but BFPs stuck around. Good luck for tomorrow!
