how to tell my mom.... 😳i'm 21.... just found out were pregnant☺️

so me and my mom are quite close, but in perfect honesty we are so alike that sometimes we do end up arguing and yelling at each other.... it's never often serious and just about petty thugs, and often fizzles out within a few minutes....

i have been with my fiancé who she adores, for just over 2 years.... and we recently started trying ...

well i just found out i'm pregnant and i am so so nervous to tell my mom..... i think she will be happy but i'm also worried she is going to freak out and worry about me so much that she will not see the good side.... and i don't want to get into an argument about it with her because it will make me feel awful😞

she lost her mom (my grandmother) in april this year and i think it would make her happy as this baby will be making her a grandmother for the first ever time.... but i'm also worried the emotions will be too much as it hasn't been that long since she lost her mom... and i feel a little guilty that i'm going to be making her deal with this....

does anyone have any advice as what the best way to tell her is...? i'm so nervous and don't know what to do? 😞
