I am 26 yrs old, married and have a child.I was earlier diagnosed of having PCOD and I normally have irregular cycles. Now it is 60 days since I got my periods. I have done a urine test thrice and all seem negative. However, of late I have developed the following symptoms: lower back pain , nausea and dizziness(sometimes) , oily skin, a light spotting twice,frequent mood swings and irritability . Could I be pregnant?
