How inconsiderate, or am I being over dramatic???? ),:

Chantelle • I thank god everyday for blessing me with such a beautiful heathy baby boy! I love my best friend👶🏽/my world💙🌍 G.C.C
I am a FTM, this will be my mothers 2 grandchild after 7 years. 
She went and called me this morning and says "Don't have Greyson anytime soon. (Even though he could come any day now) she said cause my sister planed a surprise get away for her to go to Puerto Rico April 1-8 ....my mom was so mad at them for doing that knowing that it was around my due date. But all my sister and step dad said was "she will understand" EHAT THE FREAK!?
 I immediately busted out in tears.....all I will want is my mother to be there...... I'm sorta freaking out and it's so inconsiderate for my sister to do that(she's never been pregnant and doctors say she can't get pregnant, so my whole pregnancy she hates when we're around her talking about it) idk if she did this on purpose but all I know is she doesn't give two Effs about how it will make me feel.... !!! Why couldn't she have set it up for April 20  or something...... I'm so mad and upset idk what to think, and I being selfish??? 😒☹️😔😔😔😢
