I need a little rant....

So my husband and I have been trying for a baby for about two years now, well my sister in law just had a baby in October, awesome right I’m excited to have a new nephew to spoil until I have my own babies, but now my in laws treat me like dirt..... my mother in law blames me for us not being able to get pregnant yet when I’m going to the dr, getting on medication to help but my husband still as yet to go make sure that his levels and stuff are okay. My gynecologist said my eggs and ovaries and Fallopian tubes and uterus look great... but they still blame me and say it’s my weight “you need to lose a few pounds before you can get pregnant, your to big to get pregnant” it goes on and on which drives me into a deeper depression... it pisses me off that it wasn’t this way before my sister in law got pregnant but now I’m the black sheep and I’m nothing because “I didn’t get pregnant first” like literally the first thing out of my brother in laws mouth when they were telling us they got pregnant was “haha I beat you all, my sperm is better” I was just like dude you DONT know our situation and ALL women’s bodies are different 😒... but basically my in laws hate me because I didn’t get pregnant first and the medication that I’m on to help me get pregnant could make me have multiples and they don’t want that. Whatever if they wanna be that way cool my kids will be loved my my husband and I no matter what..
