I am recently off of depo. I ve only had one dose, was due for my 2nd in February. I had one period in March that seemed normal. Two weeks before my second period was due, I had clear discharge, followed by bleeding for 1 day. Now my period is 10 days late. I have been having cramping, tiredness, and sporadic back pain for 2 weeks. I have taken a few hpt all are negative. What s going on? Could I still be pregnant?
