I got triggered today

I had 3 follicles today that were 21, 23 and 15. We decided to have a trigger shot in hopes that the 15 will grow enough to release. DH said that if we had 3 follicles that were big enough we would have an IUI, but then he changed his mind lol. Within the next few months we plan on having an IUI with Gonal-F. However plans can change, so who knows what will actually happen. I'm hoping that we don't have to worry about it and I will get pregnant, but yeah right if it hasn't happened by now it probably never will. You are probably wondering why I even try if that's how I think, but I guess it's because maybe just maybe I have a little bit of hope. I forgot to ask how thick my lining was, but 2 days ago it was 6.8 so I'm hoping it has gotten thicker. I sometimes wonder if my lining is too thin. The doctors say it's fine but I'm not sure since it seems like the majority of women who I have seen online have linings that are way thicker than mine like 9, 10, 11, 12.
