COULD THIS BE IT!!?!?!?

Carina • Age 25 / Mommy / wife ❤️ expecting my second miracle!
So I need answers and help by anyone on GLOW please !!!! 
  So October was the first time ever TRYING and doing ovulation tests; on October 13 and 14 I did my first tests and they came back negative; on October 17 and 18 they came back high fertility (flashing smiley face) (baby danced) on October 19th i took another test and it came out positive (smiley face) and I baby danced that day and the next day. My last period is was on September 27 and lasted 4 days. My AF is sometimes irregular but not abnormal. My period was suppose to get here the 4th but hasn't showed up my past two periods came out as HOW GLOW had predicted. But this time around no signs of af !!! I've had cramps days before af was due so I did think I was getting it but after that I haven't gotten any signs of af!!! Do I take a test ???? Can this be it !!!??? Do I wait???? What do I do??? And has anyone experienced this before and came out positive ???
