Still Hoping...either "natural" or adoption

So this will be my forth IUI tomorrow and I'm exited, nervous, and really hoping it will work!!! We used shots this time and there are 3-4 eggs. I just went through surgery since I had a cyst about 4cm on my right ovary. It should be good but the whole emotional aspect is killing me!!! I try not to let it get to me but almost can't help it, not to mention then the waiting to see...anticipation and let down thus far.... I don't know how many more of these I can honestly do.
Don't really know of anyone going through this now so any support, thoughts would be good.... I think it would be nice to know other's are experiencing the same or had and now have gotten through the rough part. I have no kids, been trying 3 yrs (1 1/2 yrs just us, last yr and 1/2 with doc. aimee- who is increadably awsome for anyone looking for a doc. - just to say she will personally text or call you within a couple hrs if not min, and treats you like your her only patient).
Anyways, this is my first attempt at sharing my feelings so openly...feels kinda crazy but apparently I'm desperate for feedback
