Dumb question.....

How do you know the difference between Lochia and AF:icon_question:

I had lochia for 3 weeks.... then around 5 weeks i got a bleed for 5 or so days and on/off spotting brownish dischagre then went clear....all up around 7-10 days....

Id love to know if AF was back.... would give me an indication if i should be purchasing a HPT any time soon
