Baby no3 in my 30s and w uterine polyp

So hubby came to me about trying for baby no3 years back gyno had found a small polyp which she said shouldn’t interfere w fertility but if after a year or trying she would remove it. I’m scared I am 34 and not as young obviously and i worry my age and maybe that polyp will just give me MC heartaches it doesn’t help that I’m already a pretty negative person -_- we did try once last year just to see what happens had sex on a fertile day and a day before expected period i took a test said “pregnant” but then 2 days later got my normal period so I do not know if it was a MC or faulty test either way after that I was careful I guess it just broke my heart now a yr later he wants to really try again today is the end of my fertile days we have done it from the most fertile days like 27% to 12% and today at 6% so I’m kinda scared but know deep in my heart that polyp will prevent anything from happening so I have myself prepared for that obvious thing. I don’t know if I’m asking a question here but I guess I just want to vent.

Thank You whoever reads this
