I'm experiencing something weird and unusual. I had my last period 2 weeks ago and now since a few days Im feeling some pregnancy symptoms like crampy feeling in my lower abdomen, fatigue, back ache, also experienced some spotting. I took home pregnancy test twice and they were negative. I have an 8 month old daughter and can't even think about getting pregnant so soon ???? Am I really pregnant ? Or it could be something else ? I've googled it and it says it could be 'Pelvic inflammatory disease'
