Yes, it's completely normal to be a bit freaked out by the whole thing. I was terrified that I would have some sort of bleed after the procedure or that, worse, the drugs wouldn't knock me out. Turns out - the drugs are pretty darn wonderful! The doctor was all "I'm going to administer the drugs now," I felt fuzzy for half a second, and then BAM! I was waking up and everything was over.
I agree that there is a lot to take in/consider when filling out the forms. Go with your gut instincts and remember, the risks are minimal. They just have to let you know up front to cover their own butts.
I remember feeling the same way as you after the IVF information session that my doctor requires everyone thinking of doing IVF to attend. I remember being terrified and wondering if it was worth it and feeling very down about the whole thing. But my desire to do everything and anything to be a mom won out.
I wish you all the best.
