Trying to have a baby for almost a year


I’ve been trying to have a baby with my fiancé for about a year now. My period has changed dramatically to the point where it’s like 1-2 days maxed. I got scared and went to the doctor to get hormone levels checked and get it ultrasound since I had a D&C about two years ago. Well guess what even though I have a high sex drive and I’m legitimately having sex on a regular basis, I still can’t get pregnant even though the hormones came back normal as well as the ultrasound. So it looks like nothing is wrong with me which is a good thing but now I don’t understand why I haven’t been able to get pregnant.
