Should I call for a TTC work up?

Melflower🌻 • 🌻Married // Mom 💙; ttc#2

We’re now going on 14 months TTC #2 and I personally think it’s time for me to get bloodwork done to check hormones and what not. I got my iud removed early May 2019 and weaned my son from nursing February of this year. In the back of my mind I thought that nursing was affecting my hormones and me ovulating. However, I was temping, using opk’s, taking vitamins, charting like crazy, and BD at the perfect timing each month. And I get some pretty crazy ovulating symptoms when I get my positive opk so i am pretty sure I’m ovulating. So I don’t necessarily think nursing was the issue BUT I don’t think my periods are back to what they were before I had my son. My flow is very light (more like dark brown spotting) and only lasts for 3 days. My cycle is consistent every month, i have a 26 day cycle, I ovulate on CD13 and my luteal phase is 14 days. I think it has only changed once where my cycle was 28days but that was almost a year ago. Sorry this is so long I’m just starting to worry if I have secondary infertility. I don’t think we have a male factor(he’s got two kids from a prior marriage and we have our son) but I know it could be a possibility. I would rather get myself checked first before I make him do it. He hates going to the doctor lol

What do I ask when I call for a TTC appointment? Do I just call my Gyn or do I call a specialist? Any advice is welcome.
