Recently Diagnosed with Secondary Infertility

My heart recently sank as I left the Dr. Office last week! I have been diagnosed with secondary Infertility. I’m not sure if I am welcome in this group because I do have 1 child already, but my heart is broken my husband and I each have a child outside of our marriage (8 and 6) mine being the oldest. We have been TTC for 2 years almost and it has been a hard and sad road. After switching Drs and running test I was diagnosed with mild PCOS and secondary infertility. I don’t mean to sound selfish for wanting another child when I know there are those of you who struggle to conceive 1 but I was younger when I had my first child and didn’t decide until 6 years later that I wanted to try again, and my husband and I desperately would like to grow our family by 1 more sweet little baby! I can’t help but to keep wondering what is wrong with me or what I did wrong to not deserve another baby and why was I able to get pregnant the first time so easily and not now. So many questions and I feel so alone none of my other “mom friends” or friends for that matter struggle with any of these situations. Any advice or suggestions or even encouraging words would be nice. Thank you and prayers and baby dust to y’all as well!
