haven't had period

Regina
Hi girls I am a mom to a 7 month old and I am breastfeeding I didn't have my period after labor for 5 months and then in September I started it, but this month I haven't had it yet... And I've been having wired movements in my stomach but I had an Mir last week and my doctor said everything is ok, my pelvis hurts and my movements occur not often.... Could I be pregnant ?!
