I got preg the first time I tried with both pregnancies. I kept a chart of when I was ovulating based on my periods every month for about 3 months...once I was sure I was ovulating... we had sex, and 4 weeks later I got a BFP. Also, we had sex 2 days before ovulation, the day of, and two days after... just to make sure we had every day covered. I was surprised to find that it worked so fast. Good luck to you!!
