I Took Cytotec 800mg (4 Pills) For Two Days. Then

I took Cytotec 800mg (4 pills) for two days. Then did ultrasound and found remaining part found in my uterus. I was 10 weeks pregnant. Then on the third day I took another pill of Cytotec after I knew there was a remaining part, because I wanted to avoid the surgery. Then after taking that pill a big particle/tissue fell and I bled. After that I felt very weak and dizzy. I felt like that for the rest of the day. I couldn't take another pill of Cytotec. What should I do now? Is it not safe to repeat Cytotec with no break in the middle, like have it continuously 800 mg dose every day for four days? Please advise.
