I have been testing opks since my MMC and this week they started getting darker and I've had ewcm (not as much as before but putting it down to MC). Anyway yesterday they were getting much darker but not quite positive. I'm not good at holding in my pee either so it's quite difficult for me. I tested fmu this morning (I know it says not to but I wanted to see the difference as my urine ends up quite diluted) and it was the highest it's been - a strong positive. Can you get a false positive? I'm hoping not as I've been waiting over 4 weeks for ovulation or period! Thanks.
