It really depends on the specific ingredients in the medecine you took. Bring the package and speak with a pharmacist or doctor to be sure it is safe before taking any more.

When I was pregnant the only thing my doc told me I could take for a cold was sudafed, only if I was really really sick, and she told me she wanted me to call her before I took it. I was lucky not to get sick my entire pregnancy (except morning sickness)

Before you take anything ask your .O.B. A good pharmacist should tell you that too.

Always talk to you're doctor before you take anything, only a handfull of medications are safe during pregnancy so it's best to check
