Question

So my period is almost a week late, i’ve had some cramping here and there but nothing like i normally do right before i get my period. Im not on any kinda birth control or anything and i had unprotected sex with my partner 2-3 times this month so i was sure i was pregnant, so i took a pregnancy test the first day i was late and it was negative so i gave it a few days and took another, still negative. took another yesterday and still negative. but i have all the symptoms of being pregnant, morning sickness bad too. Why is this? I’m obviously not pregnant but why do i have all the symptoms and of course the biggest one being my period is so late. Could i be pregnant? you would think a pregnancy test would be positive by now being a whole week late on my period.
