Discussing treatment plan

So I just had a 3rd failed attempt IUI and got my period Friday. So I called the fertility clinic and told them. They said they wanted me to come in and evaluate my treatment plan. So nervous about this. We were told in the beginning that the doctor would attempt 6 rounds of the IUI before moving on to IVF. My appointment isn’t until the end of July. My mind is going crazy wondering what the deal is. What do y’all think?

Oh and btw I was diagnosed with unexplained infertility. Which is the absolute worst feeling to me. You don’t know what to even do to work towards fixing the unknown issue. 😭
