Cycle messed up, Pregnant?

Hi guys!

So last month I had my period a week and a half before I was suppose to per my bc pack- heavy April 5-8 and spotted on and off for the next few days. ... and then when I was on the placebo part of the pill pack April 16-19 I didn’t bleed at all. I didn’t start a new bc pack since my hubby and I are TTC. My period hasn’t shown up yet and it’s May 14th. Every test is a BFN. Could my cycle be messed up or could I be pregnant and it’s possibly still too early if I ovulated later?
