Help...

Hey guys so I have been TTC for little over a year now. I have been off of the depo shot for almost 2 years. My cycle is very normal and has been since the month after I was supposed to get the next shot. My dr says I shouldn't be having a problem getting pregnant especially since everything seems to be normal and when I went and saw him last he said it looked like I would be ovulating soon. I just wanna know if there is anyone else who has had the depo shot and had trouble TTC after stopping it. I'm so worried I may never get pregnant. I'm 27 and my only child is going to be 10 this yr. I never wanted so many yrs between children but it just didnt work out for me the way I had always hoped. Closer I get to 30 the more discouraged I get. My dr did say I can get the IVF test done just to be sure everything is good but its 350$ and atm i just cant put out that much. I'm hoping next month I will tho. I just need some type of peice of mind idk.
