I Used 800mg Misoprostol Last Night Say 10pm To Try

I used 800mg misoprostol last night say 10pm to try to abort a 4-5weeks baby, and i had serious cramps afterwards say 2-3am and little lumps of blood came out, in the later hours of the day nothing, not even spotting on the sanitary towel, only when I wee, very drops come. Did the abortion work?
