May & June cycles

We gave in and have tried some new meds the last 2 cycles. I have taken Femara (letrazole) days 3-7 and hcg injections days 3,5,7 and 9 dpo. These are to stimulate a stronger ovulation and to jump start the corpus luteum into producing progesterone. The cycles have definitely improved, but I am not yet pregnant. They have both been 35 days long and ovulation occurred around day 20 which makes my lp go from 12 days to 15 days - very nice! I am encouraged by these things and thankful that my follicular (estrogen dominant) phase and luteal (progesterone dominant) phase are waaaay more balanced - this is so much healthier for me over all. My bbt chart the 1st cycle on the meds was beautiful and I was very hopeful. The 2nd cycle (ended yesterday) was not as good, temps went up a bit, went up some more but then by 10dpo they were dropping and stayed just barely above coverline the rest of my lp. I also had a tiny bit of spotting on 10dpo and a headache the day before menses (with migraine "aura" the night before the headache), all of this indicates low progesterone to me. So... keeping on keeping on. Sent an e-mail to my Dr and FP tonight to see what's next and if any changes are in store for the next cycle.
