in need of some positivity

My husband and I have been TTC for over 7 months for baby #2. Totally blessed and grateful for our first, but desperately want to give him a sibling. My husband wanted to try right after he was born to have them as close in age as possible. Being in Human Resources the responsible side of me said let's wait at least a year when I would be eligible for FMLA again. I totally regret that now, as he almost turning 3. He's a complete joy. Every month hat passes I'm taking a pregnancy test before my cycle is scheduled to start only to be disappointed. I went to a fertility Dr to check the boxes and everything seems fine (Maddox our first was conceived after 2months of trying). I am getting older and I am beginning to worry that maybe another is not in our cards 😞😢. Would love to hear your stories... I am attaching a picture of our main man Maddox who is the light of our lives.
