HELP I NEED HELP

I had sex the day before my app expected ovulation day. I know it's not entirely accurate but the signs were there with the cervical mucus. It was abundant and like egg whites. I started cramping 5 days after and I'm still cramping 4 days later. My boobs have been sore and tender too. I also feel very tired and barely have been making it to 6:30 without needing to sleep. I have taken 2 test so far one on the 7th day post ovulation and now today on the 9th both were negative. Was this too early? Is there a chance I may be pregnant? Should I be expecting to be?
