i’m 21 and afraid to tell my mom.

hi all! my fiancé and i are 22 and 21. we recently found out we’re pregnant with our 2nd. we tried for this pregnancy and we’re both really happy and excited. i got pregnant with our first when i was 19 and when i told my mom she flipped out. she didn’t speak to me for close to 5 months after i told her. of course i understood that it was disappointing and i shouldve ramen better precautions. she was just upset but she really did treat me differently while i was pregnant. she was there during the labor and delivery. she never left my side. she held one of my legs while i was pushing and she even cried when the baby came out. she came back at night time before to visit me and the baby. she loves her so much. i know she does. but im just so afraid to tell her about this baby because i’m afraid that she’ll react the same way as the first time. can someone please give me some advice 😭
