Any tops on the syringe/ turkey baster method?

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 use pressed a syringe prop my hips up on a pillow and wait half an hour each time any other tips? Should I use a soft cup instead? Also should I worry about air in the syringe?
