I need you’re help ladies

For the pass week or so I been having brown Discharge and having a little bit of blood spotting.

I when to my doctor and she said I don’t have any vaginal Infections so Either way they treated she gave me a pill for vaginal infection.

I’m still having a little light red color when I’m wiped my self or use the bathroom.

I don’t know what’s going on it’s my 4th pregnancy and had this spotting with my other pregnancies.

So what do you this it’s going on ??
