Anyone get pregnant from IUI?

Angela
Hi ladies. I'm 41 and have been TTC for 5 months, with a fertility doc for the past 3. All systems look good so we tried IUI for the first time last Monday. 
My boobs are so sore and I just felt cramps so I'm assuming it didn't worry and I'll be getting my period soon, which blows. 
Did anyone here get pregnant from an IUI? I don't think I'll be able to afford IVF (not covered by my insurance). 
Looking for a glimmer of hope. I got pregnant with my daughter so easily 10 years ago. I so badly want baby #2. Trying to stay optimistic but feeling broken, old. It's embarrassing.
