5 days late but 2 negative tests :c

It’s my 1st month TTC. I had PCOS prior to having my first baby. I would only have a period 3 times a year if that and then I magically got pregnant. Since having my daughter I’ve had my periods like clockwork. This is the first month we’ve been TTC and now my period is late but I’ve had two negatives. I haven’t taken the pregnancy tests first thing in the morning though so I don’t know if that could be a factor. Has anyone else had a positive after testing negative?
