Hoping there's still a chance (even though I know there's really not...😕)

So here's the deal...my SO and I have been TTC for 16 months. After my second chemical in June, we tried 3 rounds of Clomid and one round of Femara...nothing. We decided to give it a break for the rest of the year and then after the holidays save $$ for an IUI, and now I'm 2 days late 🙄 I didn't do OPKs or anything so I don't know when I actually ovulated, but I have no signs AF is coming..except for negative tests 😒

Anyone else have a similar experience after taking clomid/femara? Did it mess up your cycle? All input is appreciated 🙏🏻😊 thanks ladies! And baby dust to us all!!!
