Could I be pregnant or could I be imagining it?

Woulfe

Okay ladies so over the last two months my period was irregular and my SO and I got our hopes up so I'm trying not to do it this time around. I was due for AF yesterday; yesterday and today I have had mild cramps followed by immediate urge to frequently urinate and in the last few hours I began a very light pink spotting that only shows when I wipe as well as feeling fatigued... I took a test this morning (one of the super cheap made in China ones) and it was a BFN. Could I be pregnant and just tested too early (if so when should I test again) or is it just my baby fever making me imagine things and get my hopes up?
