me and my husband took essential multivitamins then the following month, i got BFP!
I did acupuncture to conceive first. It also took us about 3 years. Acupuncture and stress reducing activities like yoga were great although I had no problems conceiving the second...maybe your body will just do it this time like mine did. Wishing you lots of success for number 2.
I took eveningprimerose oil that you can get at Walmart and you can take that 3 Times a day from the first day of period until like 2 days before ovulation. It helps the cervical mucus build up and makes it more fertile! I got pregnant on the 4th month, but that last month was the only time I used it and I got pregnant. I noticed a lot of cervical mucus. And also I took prenatal vitamins also with it.
