Tosha... I really think they should test you for PCOS. I think if they did and then gave you a script for Clomid... it may give you the boost you need for a sticky BFP. If it is something simple that is keeping you from another baby, then why won't they just order the tests? It's frustrating. I sooooo want to see you get a healthy BFP again.
You are much stronger than I am those crazy long cycles would have driven me mad long ago. About the faint positives before... could have been either a faulty test...an evap... or a very early chemical pregnancy. If it was a chemical you would likely have had a full period. I didn't clot much with my chemicals. Either way... the last time you have those lines it was the ectopic right? I would at least get them to order a blood test to be sure you aren't PG. Some people do bleed and clot while pregnant.
I wish you the best on your TTC journey....and LOTS of
