HELP!

OK so I am in need of some support and comfort and advice right now. Terry and I have been trying for 8 mos to get pregnant and I had my first round of Clomid last month and I am now a week late. I took a preg test on sat and there was a faint line, just like when I had Madi, so then I took another one the next day and there was a line but more faint then the day before. I decided to get the digital home preg tests and they both said not pregnant. I went and had a simple blood preg test at Pioneer Valley and it came back negative. I feel pregnant like being hungry all the time, nasueas, tired, pissy at times for no reason. I am so drained by this cz I have never been more than 3 days late. I really dont want to do Clomid again cz it made me so sick and gave me huge cysts on my ovaries that hurt like a b. It was so draining being in pain everyday for 3 weeks. I know that its only my first time being on Clomid and I should prob do it again. When I got preg with Madi I had to do the laprascopy surgery to have my endometriosis removed, then I was put into menopause for  mos(which I refused to do again this time after my surgery) then 3mos later I got preg with Madi. It was a 2 year process that I dont want to repeat. Maybe im just being a baby but man this is frusterating.
Have any of you had any strange experience with Clomid?
Thanks for listening to my pitty story.
