Wow reading this thread has brought back a flood of memories and emotions. I just wanted to share my story hopefully to give some hope to others going through this journey. I started trying to conceive my 2nd child in June 2011. I fell pregnant in December 2011 but sadly had a missed miscarriage at 11 weeks. I was desperate to fall pregnant again as soon as possible and when I had failed to conceive again 6mths later I went to see a specialist. I had a gut feeling something wasn't right as my cycle had changed and I was getting more pain with my period since the miscarriage and d&c. The specialist brushed me off and told me that it was due to my age (36 at the time) that I was taking longer to conceive. I was sure there was something else going on so I got a second opinion from a more specialized fertility clinic. I started the array of tests including the HSG which showed my tubes were blocked (full blockage in one and partial in the other). In December 2012 I had surgery to unblock my tubes and had my first iui (with puregon) in January 2013 (unsuccessful) and my 2nd in February which was also unsuccessful. I had read a lot about progesterone support for iui and pushed for it in what was to be my third and last iui despite the clinic not using prog support normally for iui. My third iui was successful and I continued with the progesterone support until 14weeks. I delivered a healthy beautiful baby girl in December 2014 who is now 9 weeks old. I would definitely recommend iui and stress getting a second opinion if you're not happy with your dr. Also, don't waste time! If you think something's not right or are considering fertility treatment just do it!! It might be several months or more before you can start by the time you have all the tests done. I wish you all the very best of luck in your journeys to conceive.
