Ok a little background on me; this is a long one so I apologize. This is my first post. I'm 20 years old and my husband is 22. We have been actively trying to get pregnant for about 3 years (neither of our families know or knew that we were trying we wanted it to be a surprise). A week before Christmas 2018 I went to my doctor because I completely missed a period cycle however every pregnancy test came back negative. I'd also been experiencing sharp pain in my lower abdomen so bad I couldn't walk. This happened twice. My doctor sent me to get an ultrasound. (I got my next cycle the day after the ultrasound) the doctor told me I have numerous cysts on my ovaries and the pain I was feeling was 2 of them bursting. I've been diagnosed with moderate PCOS. (Polycystic ovary syndrome) which means there's still the possibility of pregnancy but it'll be a little more difficult. After 3 years of trying I reluctantly went back on birth control to try and regulate my hormones I also have to drop some weight as well.

Now the reason I'm writing this is because my sister in law just told us that she is pregnant and she wasn't even trying. I mean I'm super excited to be an aunt again but at the same time I'm sad and a little angry that she was able to get pregnant without even trying while my husband and I have been trying for such a long time. Does this make me a bad person?
