Extra strength tylonel ?!?!!?

When I found out I was pregnant over a month ago I went out and bought Tylonel for headaches and what not to have when or if needed. So I have taken some, but I just realized today that it's Extra Strength and not regular tylonel. I'm only 9 weeks is that going to effect my baby? Idk if there's a huge difference in them. Should I stop taking it?
