is this normal after an std swab ?

I went for an std swab today just to make sure things are still good down there , don't think I have one but it never hurts to get tested . He swabbed my cervix . Is it normal to get spotting after when I wipe ? It's normal clear CM mixed with some brown blood ... I know it's normal for a Pap but they usually scrape the cervix ... but is it normal when he just used a cotton swab ?
