Like ughhh

I was just wondering if anyone experienced sore gums and sensitive teeth before their missed AF? I am due for my AF in about 7 days and my gums have been sore for three days (however no bleeding and they look normal). This came on very suddenly and I have always had healthy, strong teeth with minor issues. Also my teeth are very sensitive, it hurt me to eat a granola bar because it was coated in sweet chocolate. Besides this I have been feeling cramping and a tight, pulling sensation in my lower abdomen. I would never think to associate my teeth with a sign of pregnancy but I have never experienced this is my life! Plus I just went to dentist 😩😩
