Hi Plopsy,
We conceived DS this way - syringe and sample pot, so it can work. We got the Lisa Saffron book, but to be honest Mumsnet has been one of the biggest helps. Sperm was at least 20 mins old, prob 30mins, and it worked. And there was lots of leakage (makes me panic!), plus no pillow (back of car ) and no orgasm.
Do check ovulations signs - my cycle is around 26-30 days but I seem to ov day 17-18. So insem around day 14 would be a bit early. Some GPs seem to insist all luteal phases are 14 days , but a quick look on the conception site here will tell you better. Mine seems to be about 10 days.
Though I conceived first time, our story is a bit like Dots - DP has been trying at least 18 mths (have lost count now) with no baby, and no tests have shown a problem. It gives me hope to hear of people getting pregnant after a long time of trying. We've decided to go with increasing our chances as we really want a sibling, and so I've started again, and haven't had immediate success this time either. So our family has the irritatingly smug first time fertility and long drawn out cynical it'll never happen fertility. DS definitely helps my partner feel better over the latter.
Oh, and zinc supplements apparently do wonders for sperm, and even if he gets tested and it comes back low fertility there are loads of things you can do to improve that and it should only take 3 months to get better quality.
Oh and I have a thing that I never can get the syringes clean so I've gone to disposables - really cheap from medical suppliers on the net.
Really great to hear of other gay mums and mums to be - we're in a fairly hetero world (even more so since joining various baby groups), so its great to hear DS isn't the only one lucky enough to have 2 mums. I hope that this month works out for you, so you don't need any more of these tips. Fingers crossed!
ps - running - DP has tried whilst running, tried whilst avoiding running, avoided and tried yoga, gone teetotal, drank loads, etc. etc. - no bloody difference, but when she gave stuff up to conceive and it didn't work she was definitely more devastated and angry. Now she's not pregnant still, but at least she's enjoying her life. Paula Radcliffe got pregnant, so I'd enjoy your life. Fitness will help you when you're pregnant.
