Thank you for the info. this is all new to me..
I've read other ladies that have had the same result with the smiley face ones. Depending on the brand and what it's detecting it could be correct, the clear blue brand is supposed to pick up extra hormones to give you more notice on when your going to ovulate, if your using clear blue then maybe thats why your getting 7days instead of 4-5.
I bought the test that has a smiley face when your at peak ovulation.. I guess my hormones are just out of wack this is my first time to ever use OPK so maybe it's normal for me only Time will tell I guess.
Opk can be tricky to read. Is the test line equal to or darker than the control line? As your hormones increase the test line will get darker, once it's darker than the control line it means your close to ovulation. You can get 2 lines on the test for quite a few days but it's only positive if the test line is darker than control line.
