Ouch pain

Goddess • Speaking the truth
??dear lord I'm in pain I am having lower abdomen pain and it's hurting a lot. No AF has come but she's light and I'm nauseous from time to time with some gas I took a test a few hours before AF so I got a BFN so I'm lost on what it can be unless its a cyst again but I'm not 100% sure at the moment just ???
