From your description, the symptoms are unspecific and could really not signify any particular condition. You might have contracted an infection most likely a UTI or PID or others etc. It could be that you are pregnant and presenting with morning sickness
. The only way to know of course what you specifically have is to get a doctor (preferably a gynobs) to examine you, run some lab tests (UPT, blood test
etc) and provide you with appropriate treatment.
Hope this helps
