Poiyt and Granite - I had a similar couldn't-believe-my-luck BFP after a first-time insemination experience - unfortunately, that one ended in a miscarriage, so then I didn't feel so lucky after all. But, that being said, I still feel extremely fortunate for my TTC experience overall, and although there was a lot of grief to deal with, it was heartening to know that I COULD get pregnant.
So, here's my story:
A friend loaned me her copy of Taking Charge of Your Fertility, which really helped me know where to begin. It isn't particularly queer-friendly, but the information is valuable nonetheless. I started charting - BBT, CM, and OPK. DP and I had a consultation with an insemination specialist (referred to us by a friend who used to work with her). Our appointment with the specialist was lukewarm. She gave us lots of useful info, answered all our questions, and provided us with a list of tests we and our donor would need to complete in order to to an insemination at her clinic. BUT, she was very critical of our choice to use a KD and wanted us to still go through a sperm bank and quarantine process. She said she MIGHT be able to make an exception if we tried once at home first, because then he could be considered an "intimate partner," but then she lectured us a bit more about the risks of a KD. We left feeling pretty certain that we would not work with her, but we decided that both the KD and I would get the blood work she recommended done anyway, and that we would try at home once first and then decide the next step.
So, 5 months after I started charting we flew our KD (he lives across the country from us) out to visit and did two inseminations - one the day before the positive OPK and one the day of, and we were all shocked when I got a bfp. As I mentioned, that pregnancy ended in miscarriage in week 9.
After my system got back on track (mostly - I went from having clockwork cycles to not-such-clockwork cycles) we tried a couple times by mail using donor home delivery, but the first time our KD mailed it with the collection tube touching the ice pack (they are supposed to be separated by a layer of foam) and the second time my cycle was a day off and so it arrived a day after I really should have inseminated. So, the next month I decided I would fly to NY and try in-person again. Once again we tried two inseminations (again one the day before the positive OPK, one the day of). I could not believe it when we got the BFP after our second in-person insemination (our 4th try total).
I'm only 9 weeks now, and I'm haunted by that first miscarriage, but I've having more symptoms this time and had a good ultrasound a couple weeks ago, so I'm just hoping for the best. If anyone wants a copy of the list of tests the insemination specialist recommended, I'd be happy to share it (if I can find it - we just moved and everything is in disorder). Also, we have two shipping packs and two bottles of the test yolk buffer from Donor Home Delivery left - when I'm (fingers crossed) solidly out of my first trimester I'll post on Queer Conceptions to see if anyone wants/needs them!
I was so thankful for the support and positivity of everyone on the Queer Conceptions forum - it really helped me get out of my head and plan and make decisions and move forward.
Editing to add: I also, upon my (naturopath) Dr's suggestion was taking prenatal vitamins, vitamin d, fish oil, b complex, iron (I'm super iron deficient) and flax. The first pregnancy my progesterone was low and I took supplements, but this time my numbers are okay so I have not taken any.
