No period since October 2018

july

Took hpt religiously from October 1st for 3 weeks because I thought I may be pregnant

"Period" showed mid October but was v light

HVe not had anything apart from vv light spotting for a couple of days a couple of times

I've had hormones tested nothing abnormal there, although they didn't test for pregnancy because I thought surely not.... now I'm starting to second guess myself... is there a possibility? Or am I just being paranoid?
