so around 12 days ago I took a pt at the doctor's which came as positive. I took the test despite getting my periods as they were 2 days late n thought that might be initial spotting. Anyways the doctor gave me an injection to stop my bleeding. The bleeding didn't really stop but it was light almost close to spotting. My MIL suggested for a blood test which gave my hcg levels less than 2 and I also took PT the next morning which came as negative. Anyways I thought this might have been a false alarm. However my spotting hasn't yet stopped its been over 12 days. So could this been m pregnant and this is first trimester bleeding which is completely normal?
