UGH- do i just give up?

So we started "fertility" treatments about 5 months ago. Since we have an HMO, we had to pay 50%. For these first rounds - it wasn't that bad... came to about $700 per treatment. We did four of them- (they only recommend four). It starts with 5 days of Clomid, followed by a shot of Menopur. Then two days later or when they tell me, i go in for another ultrasound and then i give myself a shot of HGC to trigger release. The first time, the pain was so bad.. it felt like my sides were going to split open. After that my body seemed to adjust- i had bloating and pain but not like the first. Each time I had at least three eggs that fully came to the right size. This last time i had 5. Then after the HGC shot we go in for the insemination. My husband had to deliver the his sperm in the morning and then i go in about an hour later for the insemination. Each time the number got better- first time 30% swimmers, second time 50%, third it was 60% and the last time it was 90%. I was so excited - this might happen... but then of course it didn't. So i had spoke to my doctor and our next step was to go to invitro-. We could do all shots but the increase in percentage is not much compared to invitro. So i have been trying to call to schedule an appointment for the invitro stuff and the person has no been in and has not returned my call. We are going away this weekend.. and maybe I have to wait a whole month to start this process anyway... i might as well give up soon. maybe i will give myself until december. then what do i do? i don't know... i am not against adoption but i am not ready to think that i can never have any children of my own. my head hurts now.
