Period change

Thanks to the short month my cycle changed last month I started on the 15 or the 17 and here it is tge 18 and still no period but im cramping horribly. Huuuuuuuuh is it too early to have a meltdown lol. So tired of my period in my 30s it does what it wants but im hoping this year I get pregnant and wont care anymore as long as I have my babies lol. Good Morning ladies
