Asking for my letrazole dose to be increased

MW

I just had my 2nd <a href="https://glowing.com/glow-fertility-program">IUI</a> fail and am feeling very defeated. My fertility doctor has had me on 2.5 mg dose of letrazole both tries and when I went for my ultrasounds I only had one dominant follicle both times measuring 15 3 days before the <a href="https://glowing.com/glow-fertility-program">IUI</a>.

After doing some reading I asked to have my dose increased to 5mg as to me my follicle size wasn't great and my clinic only allows up to 4 tries. The doctor reluctantly increased my dose but seemed irritated that I am asking for it. What do u ladies think? Am I being pushy or is it ok that I am self advocating as <a href="https://glowing.com/glow-fertility-program">IVF</a> is out of my budget right now so I am really banking on the <a href="https://glowing.com/glow-fertility-program">IUI</a>
