why are others pregnancies so difficult 😫

I have been trying for 12 months now, and in that time we’ve had a miscarriage (almost a year ago). A coworker was recently pregnant and constantly bragged about it, not in a nice way, sort of rubbing salt into the wound. Going on about gender reveals etc. Unfortunately she lost the baby at 5 weeks, not even 2 months ago. And I’ve just found out she’s pregnant again, she’s roughly 5 weeks again and I am absolutely dreading it coming out at work because I know how she’ll go on. I feel like I’m being absolutely awful! I am thrilled for her but I just know what’s coming and I’m going to have to smile when really I want to curl up in a ball and cry.
