Hi I'm 29 years old I already have my first child and I'm hoping for the second one. I had my period last July 11, 2011 then on July 16 up to 20 I took Ova mit (as per my OB instruction) and on July 22, I had contact with my husband up to July 30. Just wondering, I followed all my OB instruction, and done so many pregnancy test but all turned out negative. And up to now I haven't got my period. Please help, I'm kinda worried, is there something wrong? Thanks.
