Too much sugar start uterus contractions?

Today I ingested more than the recommended sugar, which has happened before. I thought that i should eat some real food to balance it out, but it made it worse. I have IBS, but it's not that because the pills i take don't help whats going on. Weak, tired, neaseated, and chest hurt, constant gagging feeling, balance is off, intestinal problems. These are normal symptoms i feel when i take in too much sugar (except the s). The abnormal part is my hurt and peeing more than usual also i have uterus contractions ranging on the left and sometimes the top or the entire thing. I have no idea what this is and have checked for previously posted questions. I'm NOT supposed to have my period soon. If anyone has any ideas let me know. Thank you.
