Would you be afraid to 'try' knowing one tube is still blocked after ectopic?

Ok! Here is the back story: Hubby and I have been ttc for over 2 yrs. After lots of blood work my former Dr had me on clomid (which we continually upped) and on the 4th month we added metformin. I got preg the first month on the metformin! However, that was an ectopic, which was devastating. Well after 'taking the summer off' from ttc and taking time to heal (I did not have surgery, just the methotrexate injections to dissolve ectopic) I had the HSG test done 2 weeks ago. The Dr got back to me today and said I still have (some?) blockage on my right side(same side as ectopic) but she felt we could begin trying again. I was surprised bc I thought I may need to undergo surgery to remove the tube. She has instructed I begin metformin again and go in for FSH lab on my next cycle day 3, and in the meantime using opk to predict ovulation and then that would be followed by progesterone lab. Would you begin ttc knowing you still have an issue w/ your right tube? Maybe I am just afraid after the ectopic. My Dr is very well respected in the ob/gyn community and I was was referred to her for infertility........ I just dont want to go through another heartbreak. What are your thoughts and opinions? It seems lots of women go on to have viable pregnancies with just one clear tube, but is the blocked tube an issue?
