Sounds as though there will be a few of us getting busy tonight!! LOL! For the first time in ages I'm feeling some mild cramping in my lower abdomen. I'm thinking this is possibly the lead up to O. I've been testing with the OPKs everyday since CD10 (because I wasnt sure if I was Oing) and they have been gradually getting darker !! I'm CD14 today. Hopefully when I test this afternoon I have a + OPK. ladies.
