When to take it a step farther

I've been trying for a for a year in May (not protecting) but taking test since August  I've been to the doctor been on clomid 3 round rounds 50mg got my "Tubes Blowed" also got a test that out water in my uterus not sure what the correct name is for it  my follicles look great as does my uterus and ovarys I ovulate regularly I'm a 31 day cycle ovulate on day 15/16 my husband has had his sperm checked everything was great ... They took me off clomid this month because it's my 3rd month and say I can get on it next month again if I like ...my question is when is it the step and what is it when should I ask about <a href="https://glowing.com/glow-fertility-program">IUI</a> IVF or anything ??? all the doctor will tell me is well just see how this month goes ... And also sense all this has been checked what could my problem be ???? I mean what experiences have you guys had ?
