Will it come??

Ok so thought i was due yesterday 29th July but still no sign. Came off the coil 2 months ago and had 2 periods since. First one was light and second was 28 days later and heavier lasting 5 days and now nothing- no cramps no other symptoms. And bfn every test! Should I be worried? Or too early? Not sure when or if I ovulated so confused right now! Either want a sign of bfp or af to start so I can try again x
