Frustrated..

Not sure what to think.. Took a pregnancy test 10 dpo and got a negative. Period started on time (Friday evening) but has been pretty light. Like today I only wore a tiny liner and only had a few drops of blood on it.. When I got pregnant with my son I had a period the 1st month I was pregnant so didn't realize I was pregnant with my son until I was 2 1/2 mos.. Part of me doesn't want to get my hopes up that maybe I really am pregnant.. But part of me is wondering why my period is this light... If it is just a legit period, then it means we're on our 9th month of trying.. Idk wtf to think anymore....
