Implantation symptoms? ๐Ÿ™ƒ

Question? I โ€œmightโ€ have had implantation pain today? I had horrible cramping and back pain for about 20 minutes and it disappeared... well tonight my nipples are somewhat sore and I am really nauseous and have a headache/feel dizzy like I havenโ€™t ate.. has anyone had symptoms for implantation or the day of? I donโ€™t have any bleeding and my stomach is lightly cramping still but not painful.
