Wishing you all the success in the world with your current cycle and let's hope you will not need to do anything further!
When not doing IVF, I am supported by the wonderful people at "Fertility Care" (Yokine). They have taught me an incredible amount about my body and my cycle. We track ovulation with signs of fertile mucus, blood tests and scans. They do their best to balance your hormones. We also do a blood test 7 days after ovulation, so that's how I know what my P4 levels are, even when not supplementing with P4.
I used the P4 injections initially, during a natural cycle (through Fertility Care) because my natural level had become so low and p4 pessaries were not doing the job successfully any more. The same thing happened during the last 2 ICSI cycles.... so they pump up the amount of P4 by number of pessaries per day, and my levels would be good for a day or 2 and then they would dive again. That's when I asked about support with P4 injections but they were reluctant but since then they've done the research. It's not something they offer everyone or on an ongoing basis, but if your situation proves to be an issue, I think there is a good possibility Dr Saba would consider the injections if you discuss it with him. I believe Hollywood prescribe them where necessary.
I don't like them mind you (they are intra muscular, in the backside!) and can ache for a day or so.
I haven't used them in an ICSI cycle yet, but may do in the next one due to previous P4 levels. However, I'm hoping my levels will be good now, given they have improved in the natural cycles.
Yes, I do ovulate, although sometimes I have an 'ovulatory event' in the sense my hormone levels do all the right things, suggesting ovulation took place, but another scan after ovulation shows the follicle did not release the egg! I have learnt all this through Fertility Care.
An experienced kinesiologist will be able to work to determine which hormones are out of balance and then improve them.
I would be happy to chat with you more, so please email me at firstname.lastname@example.org.
Best wishes for your final blood test x
