i would drfinatky bd sounds like you od do hpt and bd like crazy xx
Like mommyin10 said, take an HPT to know for sure instead of have a doubt about it....
according what you said, you started your period in April 28 (CD1) and on CD16 (May 13) you have OPK+. Today is May 18th will be your CD21. it could be to early to do HPT.
Wait at least on your CD 25-28 to do HPT.. Save you money...
Good luck to you..
Hi. It's possible that since you got a +opk at cd16, your lh surge was detected & you're about to O. I know that people have gotten +opks when pregnant & it also happened to me... If you think you might be pregnant, take an hpt so you know for sure ;) Good luck!!!
