Ttc is getting exhausting 😭

Background: I have a 4 year old from a previous marriage. 2 miscarriages before (8 week d&c; and 5 weeks natural) him and 2 after (both 6 weeks and natural. Before I got pregnant with him after the miscarriages my Dr. did every test under the sun and the only result was you have bad luck. He recommended that if I fell pregnant again to take 1 baby aspirin a day. I did when I got pregnant with my little one. Carried him to 39 weeks. 2 miscarriages after.

Fast forward: my little ones dad and I divorced and I reconnected with a childhood friend, fell head over heels. We've tried for almost a year (next month will make any year) and nothing. Not ever a maybe. He was previously married and they had tried for a few years. They did the whole nine yards, climoid, iui, ect. She got pregnant twice both were tubal. After talking with him I learned he had low sperm mobility. 🙁

I am convinced I'm just not a good baby maker. I go Oct 10 to my obgyn who told me if I hadn't conceived before then we would start out options.

I'm so sad as my little one is about to turn 5 and I really wanted him to have a sibling to grow up with.
