 [ Symptoms ] what happens to your bones during pregnancy and breastfeeding [ Disease ] i had the same experience but i was 16 years old the way i did it is that if she knew you were sexually active she has it in the back of her mind that one day her little girl will not be little much longer so the way i did it was i just came out with it i made sure her mood was right the vibe was good and just came out with mom i am pregnant  she may be disappointed for a while but she will grow over the idea my mom was pissed but i was 16 years old now i am 23 with 4 kids all with the same dad and we had been together since my first so i would either do the flowers but put in the note or whatever im pregnant lol or just tell her because if you hide it than it just makes everything worse so just tell her
