What do you think it could be?

Period is due today. Around 9 am I wiped and got some light pink spotting. So I was like ok it’s my period… 5 hrs have passed and every time I been to the bathroom I been getting pinkish spotting and little but still no flow. Usually after I see spotting I get my regular blood flow for my period.

I don’t think I am pregnant but just a little scared because I’m not in any type of birth control (we use pull out method)

And yes I am married and if I was to be pregnant I would be ok I’m just not planning another pregnancy right now.
