Someone please give me peace of mind...

Long story short, I’m 5 weeks pregnant and I’ve had painful anal bleeding with bowel movements (it’s called an anal fissure). So I remember my Dr. saying with my first pregnancy that Colace was safe to take during pregnancy. So I have taken 1 everyday for the last 3 days, but now I read 1 negative comment about it out of the 100 and of course I’m freaking out now. I’m one of those people who freak out about medication during pregnancy, but was so desperate and in so much pain. Give me peace of mind that I didn’t cause any harm, please...
