Ivf or unblock tube?

Hello I'm 32. I had a <a href="https://glowing.com/glow-fertility-program">iui</a> two months ago then two months just on the fertility pills no success. I went back to my dr. He's recommending <a href="https://glowing.com/glow-fertility-program">ivf</a> . He put me on birth control pills just in case I want to do it this month. Total cost 12000 . I wasn't able to get a loan. Now my question is if I should wait to save the money, I'm thinking this summer. Or should I just have my fallopian tube unblock. Has anyone had it unblocked? And how many months after that did you get pregnant? I just think that <a href="https://glowing.com/glow-fertility-program">iui</a> will not work for me .I think I will stop the birth control pills , it's causing me nausea. :(... another thing is I hate needles I don't think my husband and I will be able to handle them.another question how much is the procedure to unblock the fallopian tube and has anyone had any issues? Is it risky?
