I don't believe WE have anything that is within our control that impacts getting pregnant. I believe sometimes you get lucky and you find the right sperm and the right egg and the right embryo and you get pregnant.
I have been through 5 fresh cycles of IVF, 1 frozen cycle of IVF.
On my first cycle of IVF, I ran the entire time, I drank the entire time, the only vitamin I took was a prenatal vitamin, and I continued to drink caffeine. I got pregnant.
On my second, third cycles of IVF, I did not exercise, I did not drink alcohol, I did not drink caffeine. I did NOT get pregnant.
On my fourth cycle of IVF, I did not exercise, I ate full fat cheese, I did not drink alcohol, I drank caffeine, I took a TON of supplements (DHEA, CoQ10, Royal Jelly/Bee Pollen, etc.), I used accupuncture. I did NOT get pregnant.
On my fifth cycle of IVF, I walked for exercise, ate full fat cheese, I drank too much alcohol, I did not drink caffeine, I took a TON of supplements, I used accupuncture. I got pregnant.
There was no rhyme or reason to my success.
My first IVF cycle was when I was 29. My second through fifth cycles of IVF were when I was 32.
