TTC after mtx shot

Lauren • 34 married w/ DD and rainbow DS. Ectopic preg in 2014.
Not sure if there are many ladies in here but I'd love encouragement if anyone is reading this! I had an ectopic in mid-Sept and got the mtx shot a few weeks later. The doc has given me the okay to start TTC again later this month. I am so incredibly nervous and feeling so much pressure (that I put in myself). I am so afraid I will "fail" again. This should be a fun time but I'm feeling too anxious to focus on anything else.
