Two ectopics :(

I've had two ectopics :( both cornual. Plenty of tests - no reason found, clear tubes, no scarring, no sti's etc etc. I just don't get it - I'm in my third month TTC again after a 3month gap due to the methrotrexate. Feeling so disheartend :( will this ever happen for me??? I miss my two beautiful babies that got lost along the way xx
