1 week SPOTTING, 1 week Period and 1 week spotting AGAIN after period. HELP!

Hi! I have irregular period. But this is the first time happened to me, 1 week brown spotting before period approx Nov5-nov9, then 1 week period approx Nov10-18 and brown spotting again approx Nov19-now. I had unsafe sex on Nov 23 (even im spotting) then after our sex, me and my bf noticed light red blood (not the brown spotting anymore). Then next day of our sex, the light red blood turned into brown again. I dont feel any pain, no smell at all. Does someone experienced this also before? I am worried that this may be a serious problem.

I've experienced strange off and on spotting before, and it turned out to be nothing. When I was pregnant I had no spotting at all.

Spotting could mean so many things, and I doubt you'd be able to get any kind of diagnosis on spotting alone.

Don't panic, it's probably nothing, but just to put your mind at ease do a pregnancy test and follow up with your doctor.
