I usually dont get up until the next morning but i dont use a pillow so i think ill start using a small one we have and sit on it ive even laud down with my legs on the wall lol

After sex don't stand up and walk around. Lay in bed with a pillow under your hips so your uterus is tilted, I read that helps. Probably for like 10 minutes after... Not sure exactly how long but if you get up it's harder for the sperm to swim to the egg because they have to swim up, doing the tilt gives them an easier journey. Good luck, hope you get pregnant soon 😃
