I just need somewhere to get this out

Backstory: My step sister is a truly terrible person. She has four kids by three different dads and was so terrible to them that she no longer has coustudy. The younger two live with my mom. It took my husband and I three years to conceive my now two year old son, but in the middle of my miserable struggle she found out she was pregnant for the third time. I was the worst mix of angry and sad and it was a very hard time for me. Current day: She since then has had two more children she presided to starve and abuse. 6 months ago my husband and I decided to start trying for baby number two. It didn't take long to figure out I still don't ovulate on my own so I'm back on the Clomid rollercoaster, peeing on stick after stick, telling, tracking every p freaking hour of your cycle, and scheduling sex with my own husband. BFN after BFN and today I found out that that fucking bitch is pregnant again. I can't believe this is happening.. AGAIN. This world is just so unfair sometimes 😢 Anyway, I'm sorry for the poor me post. We just haven't told out family and friends about us trying because when it did happen we wanted to surprise them this time, so I can't vent anywhere else. Baby dust to all you mommas out there still trying, I'm just feeling extremely defeated 💔
