Are you doing anything to track ovulation? Such as OPKs or temping? It's way better to know when you ovulate and have a ton of sex then instead of just doing it a lot over the span of 10 days. It's also best to have sex the day before ovulation, so that the sperm is waiting for the egg. Good luck!!
There are a few lucky ladies that get their bfp at 10dpo and other have to wait till they have missed their period. I would say to be save and not get disappointed with a bfn, try to wait till about 12dpo and so on...good luck
I should also add that i have been feeling some weird pressure in my lower abdomen along with slight cramping on my left side. Not sure how fast you can feel pregnancy symptoms after conception. I cant remember with my first 2.
