K.,
Sorry that you are having such a hard time getting pg this time around. I know exactly what you are talking about. Even though we are no longer ttc, it took us 7 years before we finally conceived triplets which turned into a twin birth.
I had never heard of Femara, so I looked it up on the web. It is similar to Clomid, which is what a lot of women take, and I didn't respond to it at all. I, personally, have issues with these kinds of drugs...if they are given by your ob/gyn, which is usually how it starts out, you are not monitored closely enough and you end up loosing months beating your body against a brick wall. I did 10 rounds of Clomid, and still didn't get PG, and my tube was clear.
My first question to you would be is your doctor a "fertilty specialist" as in an ob/gyn that specializes in "fertility" or are you seeking a Reproductive Endocrinologist? Since there is a HUGE difference in the two. It sounds like you are just seeing your ob/gyn, if it has been 13 months and you are still on Femara and just now getting to the HSG.
A lot of people don't have IF coverage, so it can be quiet costly. I hope you have great coverage, because if you have to go further in your IF struggle, an RE & other ferility treatments are not cheap!
As far as the HSG is concerned, yes it is to check to see if your tubes are open or not. I had one done a long time ago, while I had ovarian drilling done and was a sleep so I didn't have the uncomfortable feeling it can cause. I have heard that it isn't painful, but if the gas is not all pushed out, it can be uncormfortable. It is usually done as an outpatient procedure. Here is more about it from Web MD (http://www.webmd.com/infertility-and-reproduction/guide/h...)
If you need anyone to talk to, you can e-mail me personally at ____@____.com and I will gladly give you a listening ear. Since I know ttc can be so irritating and if you don't have anyone that has been thru it, it can be a lonely road to travel down.
Hope this helps and keep us posted. I will keep you in my prayers.
Take care,
God Bless,
J. D
