Should I be scared to tell my mom?

Cierra • TTC Baby #2 for 5 years now. Just finished battling Complex Atypical Endometrial Hyperplaisia and starting fertility treatments!
My husband and I got pregnant on our honeymoon and were so beyond excited. However I was terrified to tell my mom and for good reason. She was very unsupportive, told me I had ruined my life, and even suggested that I get an abortion. At that time I had been with my husband for over 6 years, had graduated college, and we were married. It was so hard to know that as a mom to be I could not rely on my own mother for love and support. I cried myself to sleep every night for two weeks and didn't speak to my mom for two months. She ended up being nicer and apologized and is in love with my daughter but I am TERRIFIED to tell her we are trying for #2 not to mention telling her I'm pregnant again. . .it shouldn't be this hard right?
