Wow I am glad I went for the scan. About CD12, lining 8mm, and THREE mature (20mm+) follies. He sent me away without a trigger, and with a stash of condoms. Apparantly we can try on our own if we want but he is advising against it. D'oh! Makes me reconsidering taking it unmonitored, I was only on 50mg CD2-6. Next (monitored) cycle I am going down to 25. Darn PCOS.
