when to start ttc

I just got married at the end of march. I've been with my husband for almost 5 years. We have lived together in total for almost 3 years and have owned our house now for almost a year. I am ready to start TTC but my parents were less supportive and excited than I had expected. I decided to go off my birth control this month and I'm second guessing everything. Has anyone else gone through the same situation? Or just have any advice?
