Hello! So my husband have been ttc for over a year and been on chlomid for 5 months. My period was due in thanksgiving and it still hasn't shown. I have taken two pregnancy tests one at 6 days late and the other at 9.... both negative. And my doctor says he wants to wait a while longer before a blood test. ...any ideas? I have been really tired, slightly light headed and gassy....tmi I'm sorry. But this are really the only changes. ...
