What is the effect of cytotec (misoprostol) on a fetus?

Not good. Cytotec (misoprostol) stimulates strong uterine contractions and can lead to fetal distress or even demise. It can be safely used only in minimal doses under experienced physician supervision. If one takes it to cause abortion without success, the fetus can have moebius syndrome (facial paralysis).

I used cytotec (misoprostol) to abort but didn't bleed. U/s showed 5 weeks and 6 days fetus but no heartbeat. Will 7 weeks fetus on next ultrasound have heartbeat?

Time will tell. No way to predict. If your dates were consistent with a 5wk6d pregnancy chances are pretty good. If the fetus is alive then there should be definite fetal heart activity visible at 7 weeks especially with a vaginal scan. Hope things work out the way you want.
