Twins!!!

So today I went to the doctor to get my first ultrasound done thinking honestly if I was going to keep the baby or not.... I have always been 100% against abortion but seems how I am divorcing a very manipulative narcissistic butt hole who was not safe for me to be around anymore with two children already from him I was contemplating. Little did I know when I saw the ultrasound today I am carrying twins!!!! Twins!!! Yea you read that correctly!!! There aren’t twins in my family nor his!!!! Idk how this is possible..... I am keeping them but still idk how it’s possible!!! One measuring 5w5d and the other is measuring 5w1d. This is crazy!!! 2 separate sacs!!! 2 separate babies!!! Holy cow!!!! I am scared and over the moon about it at the same time!!!
