Can u take an OPK early afternoon and test negative but later in the evening test positive? I took a test earlier today and was negative but it was SO close to positive. I wanna test again but think it's excessive lol.
Yes. U can get a faint positive earlier in the day and a positive later in the day. When u do get a positive u will ovulate usually within 24-36 hours and ur egg will be "available" for 12-24 hours once it's released
