Insemination questions/help

Alycia

Me and my wife are trying to convince and we want to do an at home insemination does any one have any suggestions.

We tried oct14th with a 10ml syringe and after a week i was getting pregnancy symptoms (sore breasts, nauseous, back aches..) i tested the 28th of October and got a negative. Could that be because it was too early? I also am 3 days late.
