TTC right after stopping birth control pills

Nena
Hello! This is my first post. My Husband and I just got married last month. I stopped taking my last pack two weeks prior to my period week. We went on a small little getaway to the lake house and we had sex all weekend and he came inside me. I had my period as normal. Then during the whole month of June we had sex frequently throughout the month, and during my fertile week in which he came inside me again. This week AF came. I am a teacher so I am hoping to get pregnant sometime within the next couple months. However, according to my doctor, there is a chance of my body releasing multiple eggs (like 2) at a time in response to stopping my birth control. Is this true? Is it possible to have twins because of this? Has this happened to anyone here?
