Flare cycle without pill?

[Sara69]

Hi,

My IVF cycle was cancelled because of too low E2 levels and only two follicles.

Was wondering is anyone who has doen a flare/anatgonist cycle can help me understand the email from my doctor about my options - is there any issue with implantation (because of progesterone levels) if you don't go on the pill before an antagonist cylcle?

I'd like to go with my doctors recommendation to wait for my next period but don't want to go on the pill after that.

This is her letter:
To get started on another cycle we have 2 options. Ideally a flare cycle coming off the oral contraceptive pill is the preferred option, as a flare cycle run off a natural cycle runs the risk of having as progesterone rise, during the cycle. This ultimately may affect implantation. In your situation now, we could commence the pill now for 3 weeks and than cease it to get a cycle start. It may be better though to wait to get some of your own pituitary and follicular activity back. This would mean waiting until you get another period, which could be 4-6 weeks and then starting the pill for 3 weeks.

The other cycle option, is an antagonist cycle. In this cycle we would wait until you get you period, and then start the FSH on day one. Instead of Lucrin, and antagonist called orgalutran is started on day 5. This cycle allows less suppression of the pituitary and would get us stared sooner. Looking at both options, I think at this stage the second option is probably preferable.
