What Are The Side Effects Of Using Misoprostrol Tablets?

Hello. According to the website Women on Web, I need 12 tablets of Misoprostol(Arthrotec) to do an abortion. But I only used two. I took the other one orally and put the other to my vagina. It s been 4 hours and I feel all the side effects mentioned on the said website yet there s no bleeding. Just some white slimy thing keep coming out. What should I do? Please help!
