2nd round clomid fail 😞

So I tested this morning for my 2nd cycle of clomid and it was BFN. I’m crushed. 1st cycle I was on 50mg and this cycle I was on 75mg, ovulated both times. Clinically I haven’t been “diagnosed” with anything so wtf gives!? I’m so crushed and pissed at the same time. Do I try for a 3rd round or just pay the extra $500 to start doing <a href="https://glowing.com/glow-fertility-program">IUI</a>? Any 3rd times the charm success stories?
