Hello I’m 21 years old weighing 130 & I’m trying to have a baby.

I tried this month and failed. Can someone give me some good tips or tricks. I heard if I couldn’t get pregnant within 3 months I should see a fertility specialist with my age.

I track my ovulation

I take vitamins

I get enough sleep

I eat fairly healthy

I would just love to be able to get it this month when I ovulate
