wtf? tmi

Stasi • I`m 26, husband and I have been ttc for 4 years for baby #1
Had my last period on August 31st (28 day cycle) and I started again yesterday September 16th. My question is why am I bleeding again after two weeks from my last? Googled what it could mean and it says ovulation spotting (and I'm not spotting) so crossed that out and the other one is menapause I'm 26. What do you guys think it means?
