Using the syringe method! Any success stories or helpful hints?

Britney • I'm a happily married to the love of my life and I'm a 27 year old who is graduating university soon this year and is hoping to start having some beautiful babies soon! We have had one pregnancy and miscarriage at 7 weeks so far hoping for a rainbow baby
We have been having lots of issues doing it the natural way because of medications but this is working great for us so far! Much better being inseminated everyday in my fw then twice or three times all month and hoping for the best! I'm worried about the speed of putting them in a syringe might damage them but I know I'm prob being paranoid lol any tips or tricks or success stories? We are also using preseed and I put my hips up for half an hour afterwards
