So I made it through the testing gauntlet. Suppression check looked good and so did my endoscopy (though the biopsy results aren’t back yet). So, I started medications to prepare for FET  #4 last Saturday.

So, for three days I’ve been on an estrogen patch, letrozole, and am back to the daily leuprolide acetate at half the dose I was at before. Apparently the letrozole is specific to a protocol for women with endometriosis. Haven’t started crying randomly yet. (That’s what happened last time I was on estrogen patches.) I’m also in the middle of tapering off of the benzodiazepine that I was on to counteract the side effects of the lupron.

Trying to hang in there and cut myself a break every now and again, but it’s also exciting to be proactively doing something again. I calculated my chances of pregnancy over several transfers. I took a percentage on the conservative side of the range for my chance of conceiving per embryo. I put that at 20%. So each transfer of one embryo, I always have the same 20% chance. However over time, my chance of getting within that 20% increases. I actually found the formula for this on a website calculated the chance of different bosses dropping loot in WoW. LOL.

Here it is:

1 – ( ( 1 – x ) ^ y )

So, using this formula, I calculated my chances for this transfer with two embryos is approximately 36%. If I transfer all six embryos (not all at once) at my current clinic, my chances are about 74% and if I transfer all nine that I have on ice we’d be around 87%. My partner then pointed out we should include all of our previous attempts (six embryos). That would put us at a total of 15 attempts, each with the more conservative 20% chance of working out. Plug that into the formula and we get a 96% chance. Of course that doesn’t take into account the long journey we’ve had to find the possible cause of our infertility (endometriosis). The treatment of that underlying factor and any other factors that we might not know about.

Still, a girl’s got to hope. I’d say these are some pretty good odds of a legendary loot drop 🙂

By the way, here is that probability formula graphed: my chances are beautiful….
