Trying preseed

So we are trying preseed for the first time. I am a super early ovulator so we have to start on about day 8. We didn't pre inject it cause we are 69ers and I don't want him eatting that ewwww. So I put some on his bizz when we were done with for play and getting down to business. After he ejaculated in me I layed on my back and put it 1 and 1/2 g's of preseed and layed their for 30 mins playing games on my phone. I am hoping this helps us this cycle.
