tikamom: Welcome to the boards!!! You are in the right place. I SOOO wish i had the support of the women here for my first cycle.
OOOH, where to start re: advice, tips pointers. Hmmmmmm....
1. Never be shy about calling fertility center w/concerns or questions. You are paying them a lot of $, and it is important that you feel comfortable with what you are doing. Ask your RE lots of questions...that is part of his job.
2. Don't take yourself too seriously during cycles. If you are anything like most of us, you will be on an emotional rollercoaster during and after stims. I chalk my moods during that time up to the meds/hormones, and know they will change soon enough (like the wind!!!), so try hard not to take them too seriously.
3. Find a thread that will be cycling at the same time as you. Esp as it is your #1 cycle, they will be able to help you with questions, concerns, be a shoulder to cry on and vent to.
4. Keep a schedule for yourself. Now, maybe this is important for me as i am neurotic... so you can take this w/ a grain of salt.... but i have a notebook where each page represents one day of stims, on it i have what meds in am and pm, along w/any appts. I keep this on the counter in my bathroom right next to my meds. For me, it was helpful so that i felt i was on top of what meds, when, etc. At the back of the notebook, i would write an entry every few days re: how i was feeling, how appts went (i.e., us results w/follicle sizes, etc). It was a good release for me, but also was helpful going through cycles #2 and #3 to be able to go back and compare results as i went through stims.
5. Connect w/dh. This is his process too, but most men feel helpless as they have to watch us go through this difficult time. Don't necessarily use him to vent (that's what these forums are for

), but keep him posted on how you are doing so he can share in it with you.
6. Try to find balance in your life. IVF is a very intense experience that can easily consume you. I did 3 fresh cycles back to back and felt when i was done, i emerged from an "IVF haze". I did not do a very good job of continuing to pursue other interests, etc. Everything was about my IVF cycle. Now that i have had some time off and done some soul-searching, i have things back in perspective.
7. Be careful who you tell. My #1 cycle, i did the "classic 1st timers" mistake and told all sorts of people. As a result, i had people calling me everyday wanting an update. I think it fed my obsession w/IVF... and also made it much more difficult when the first cycle tanked. So just be conscious about who you tell, and be sure they will be supportive.
So that is all i can think of for now... my 2 cents worth. Lessons i learned from doing 3 cycles. Hope it helps.... and best of luck!!!
ooh, and as for OHSS, it is not very common to have a serious case anymore (my RE says he hasn't had one in over 10 yrs). Mild or mod cases can occur, but your RE will know during stims if you are at risk... so be sure to ask him if you are concerned.
