I went on the "my monthly cycles" forum which calculated that I should ovulate Friday (yesterday). BUT earlier on in the week I took an ovulation test which detected my LH surge on Tuesday, I tested again on Wednesday and the line was still saying that my LH surge had started. SO we BD Tues, Wed, Thurs but not Friday - do you think this is okay? My period was late arriving last time (first time ever) so this may have messed up my ovulation prediction (on the web) a little.......WHAT DO YOU THINK GIRLS? P.S This is sooooo damn scientific! It is ridiculous! My bedroom is like a sciene lab! AAAAAAAAAAAAAAAAAHHHHHHHHHHH!
