I am using a private sperm donor so I use the 'turkey baster' method.
Here are some tips.
-After collecting the sperm, let it stand for about 10 mins as it'll be easier to suck up the syringe.
-When sucking it up the syringe do it very very slowly otherwise it'll get killed off.
-Lay down with your hips/bottom raised, place a few pillows under there, that helps.
-Insert the sperm filled syringe and press the plunger slowly until it is pressed all the way
-Then either leave the syringe inside you and lay there for 20-60 mins, hips raised still. Or use a softcup to keep the sperm where it should be and not have it leak out.
Keeping the syringe in acts as a plug for the hour you're lying there so that helps a lot.
I know many many ladies that have gotten pregnant using AI so it definitely does work.
That's about it I think.
If you have any questions or need to talk feel free to pm me.
I know my situation isn't quite the same as any of yours but we are all doing AI (artificial insemination) so it's the same in that way
