I love this site and was always checking it out for inspiration. Hopefully, you see something in my story to help you with your journey.
I have no fertility issues, except I married a woman and our sperm needs to be purchased :) And I started this process at 39, now 40. My first 4 cycles were with Clomid days 3-7 and an Ovidrel trigger shot prior to the IUI. I usually had one, maybe two mature follicles anywhere from 16-26mm each cycle. The second cycle resulted in a chemical pregnancy and a cyst that required us sitting out until it resolved on its own. So, after 4 iui cycles and a discussion with our Dr, we decided to get more aggressive and move to injectibles and back-to-back iuis. The Clomid was giving me some nasty headaches and I don't think it was helping my lining either (always around 5-6mm). Cycle 5, I started Bravelle injections (75 units, which is one dose) days 3-8, then Ovidrel trigger, then back-to-back IUIs (24, 36 hrs after trigger). One follice at 22mm, lining around 8! But, no dice.
Went right into the next month with the same plan, but upped the Bravelle to 150. This was going to be #6, our last shot! Bravelle 150 injections days 3-8, Ovidrel trigger day 9, back-to-back IUIs (16 hrs and 40 hrs after trigger). One lonely follicle measuring 18 at two days before the IUI, and my lining was over 9. It only takes one, right?
I was trying to chill out this cycle and relax. I was preoccupied most of the time and I rather casually decided to poas the evening of the 9th DPO. It was a light positive. It really threw us for a loop, but we stayed pretty calm about a light positive. It was early. Of course, I didn't test the trigger out this time, but it's usually gone by dpo6. We also had that chemical pregnancy and knew if the line doesn't get darker, it might be an uphill battle. So I kept poas every day :) The line got darker around 12dpo, so then, on 13dpo, we got the digital positive! My beta number at 17dpiui was 500. This was it. At 6 weeks, we saw the heartbeat:)
No symptoms during the two week wait with one exception. My boobs were SORE and swollen at the end of the first week. Never had that before. The only thing I did differently was to relax. I know, everyone says this, and it sucks because when you tell someone to relax, it is akin to saying "don't remember the number 116." The only thing you can think about now is '116.' But, I just lived my life during the 2ww. I had a couple glasses of wine (not all at once, I wasn't crazy:) and after the positive at 9dpo, NO booze), I stayed up late, and I didn't read the internet about the 2ww:) Honestly, there was nothing left for me to read. After 6 iuis and almost a year of trying, I found the end of the internet.
Live your life through this process to the best of your abilities and have a plan if things don't work out. Having that conversation with your spouse early and in-depth was the best advice I was given. It helped me to really chill out the last two cycles because my wife and I sat down and discussed our course of action for our entire family plan, to include how many IUIs I would do, if IVF was a consideration for me, when she would try (the benefit of having another uterus in the family), etc. Having that in-depth conversation put my mind at ease for the rest of the process because I knew if this stage didn't work out, we were already in agreement with what was next.
Good luck everyone!
