No your not pregnant how could u be pregnant when u had ur periods after fingering. .....back ache and nausea may be from other reason but not because of pregnancy......!
No, you are not pregnant. The backache and nausea are normal effects of a period, so maybe that is what is causing it. It could also potentially be psychosomatic, which means that you are thinking you may be pregnant so you are making your body feel these symptoms. I really wouldn't worry about it. The test was negative and you aren't going to pregnant by being fingered.
