3rd round of IVF high dose

Hi all! So I am starting my 3rd round. The first two were cancelled because I didn’t really have anything happen from meds. This time I was put on 100mg Clomid and 450 menopur which I believe is the highest. The other two rounds I did 150 of menopur. Last night was my first night. Granted today is the last day of my period I feel like I am already feeling a little Bloating and slight cramping in my uterus. I am scared because it’s only day 2 tonight. Is this normal? Will I be able to make it to like day 10-12? I am also scared of the side effects to come. Any words of encouragement or positive thoughts or anyone that had similar protocol? Thanks in advance.
