13 days Late period

Nydaysha

So my boyfriend and I bd on the 13th of January and I supposed to came on my cycle January the 26th and it never showed up , I’m almost never late on my periods and we was both excited about me actually missing it because we’ve both been trying for a baby , but I took a test on the 29th and it’s showing negative 😞 should I test again ?? I have been feeling weird though like my mouth gets watery like I wana throw certain food up after a certain smell , peeing a lot , and I’m always tired
