not sure how I feel

Probabaly just me being frustrated in my journey of infertility but when my sister in law start posting on fb about her #pregnancyprobs or #pregnancycravings and she only 8 weeks pregnant now currently 15 it's only makes me upset and wanna hide her posts. Like I feel it's being rubbed in my face? Not trying to be a Debbie downer but she knows what's I've been going through and continues to do it. Currently ttc for 3 years now.
