Hello Doc, I had a mc in early 2013, after which hubby and I planned not to try for a year or so as we wanted to take time before having a kid. Decided to start trying again in dec 2014. My doc started me on siphene 100 in Dec. No pregnancy. In Jan, started siphene on cd1 followed by follicular study. One Follicle seen starting cd14, 2 dominant follicles from cd15. Both grew in size up to 34x22mm and 24x17mm on cd18. Ruptured only on cd20 and no pregnancy. Do I need a higher dosage of Siphene? Also, as I started on CD1, and still ruptured only on CD20, should I follow start clomid on any other day for this cycle. I am already on CD4 today.
