Our Dilemma

Yesterday was the first time we have ever made it through an OB appointment without me leaving in tears!  I think we're making some progress here, people!

Here's the gist of everything:

My doc says he wants us to try and ignore the cyst for now and start injectionables for this upcoming cycle.  If the cyst grows, we can stop and make a different plan.  If it doesn't, we can continue on and try to inseminate by Mid-March. 
He scheduled me a progesterone blood test for Tuesday to make sure I'm ovulating (just somehow missing it on the OPKs) and then start an intense round of Menopur.  The good new is that injectables increase your chances of getting pregnant and you are constantly monitored throughout to make sure everything's going according to plan.  The bad news is there is a higher percentage of having multiples!  Ack!  I can't imagine having twins, much less becoming the next Octomom!  No way!  The very thought of multiples makes my head spin.   
But, I really want to get pregnant and I'd love to do it before I'm forty.  
But I hate drugs!  I rarely take anything for pain and prefer to tough it out.
But I know someone who got pregnant after injectables and had ONE, perfect baby boy!
But, needles, yeeeesh.
Aw, but twins would be adorable and we could be done making babies.
But TWINS??!!  Good gawd I'd rather stick a hot poker in my eye. 
Do you see how my mind works???


So here's our dilemma...
Do we bite the bullet and take our best "shot" (no pun intended) and go for the injectables?!
or
Do we try one last natural cycle in hopes that the HSG, new donor and 2 month break is the recipe for success???


I could really use some advice.
