yeah I just had my third dose of methotrexate and they told me to wait at least 3 to 4 cycles before conceiving. let me know how things go though, I'm trying to get back to 0, just went from 2400 to about 1400 hcg in one week so I'm praying it goes down quickly cause then I want to try again after a few cycles!
I wish you the best of luck
