Hi , during first trimester i have taken lot of panadol (acetaminophen) and daflon overdose afraid something could happen to baby?

Relax: Most of the time, things that you did before you found out you were pregnant do not carry significant problems. If a baby survives the first trimester, chances are the baby will be fine. It's too late for you to do anything about it anyway, so relax. As an example, even though smoking cigarettes, drinking alcohol, using cocaine increase risk to babies, majority are still born normal.
