I'm so sorry in advance to those who've been trying for longer than I have, so I shouldn't be upset about this, but I wanted to know what could be the reason why I can't get pregnant fast? I don't have PCOS, Endo, or PID. I only have a vitamin D deficiency but I'm taking medicine for it. I might have a thyroid problem, but I'm not sure how that's a factor. I'm obese. 20 years old, 208 pounds and only 5'4. I have a regular cycle, 26-28 days so I know I have to be ovulating. It's so frustrating.. does anybody else have none of these and still isn't getting pregnant? My partner's health is great. No low sperm count, he has no issues. He also has 2 kids too.
