hi, i came off the depo inj last april and my periods did not return until about 3 months ago, even then they were irregular i had them every 2 weeks. i have not had a period now for over a month except for a little light bleeding about 2 weeks ago which happened after sex and lasted a day or two. i have had slightly tender breasts but not majorly so, also i have had some slight nausea and some dizziness, i have also had some fatigue i have taken about 5 hpt's all of which came back negative but i still feel pregnant, is it still possible i could be so?
