What can I expect?

My partner and I are not TTC and have been using the natural pullout method.. I've felt for the longest it's hard for me to get pregnant which is great atm but this month, I've missed my period for almost 3 days now.. I was irregular before until I started tracking, it's been fine and there was a month where I missed it for a day or two but I don't think it's been this long.. I'm also having some White discharge for 2 days now, plenty enough to wear liners. Anyone know what's going on? I doubt it's nothing but some of you may have gone through what I'm currently going and can give me advice. I have not taken any tests yet and I hope I don't have to. Any info helps, thank you.
