Yoga and Conception

My doctor is not for opks or ovulation apps she told me to have fun, have sex a lot and do yoga and she guarantees I'll be pregnant within 2-4 months. She also recommended I take pre natal vitamins and eat healthy and drink water. She said thinking about Ttc does more harm than good and throws off your ovulation. I'm gonna hold her to that timeline. It makes a lot of sense to me. Every time I read someone didn't get pregnant I stress, when someone gets pregnant I get sad. It's a lot. I'm gonna put it to the test and keep Everyone posted.
