I know some woman are like this isn't true .. Actually that's how I knew I was pregnant .. If you look through my post you can see I made a post about this last week sometime .. Around 10 DPO I decided to pee on a OPK because I was bored and the test line was so dark 😳 so I did some research .. And I found an OPK can in fact pick up hCG .. Now I'm not saying it's reliable in all cases but from 10dpo till 17 (which was last night) I kept getting positives even though I know O'd on the 7th.. Some woman said it will be positive before a period (I tested this out last mth and it was negative 2 days before my period arrived ) not to get anyone's hopes up but they worked in my case .. If you get a positive OPK for hcg it will surely pick up on a pregnancy test .. I could have tested positive on a pregnancy at 10dpo but I waited it out so I wouldn't be disappointed.. I did get a dark positive last night .. Just thought I'd share ! Good luck and baby dust to all 😌
