Pelvis pain on right hand side

Nina

Not sure if I’m pregnant I’m breastfeeding my 13 month old.. but I’m on no protection and I started brown spotting 2 weeks ago. And not I’m having twinges and sharp pains in my right side of my pelvis (bearing in mind I don’t have a tube that side) and also haven’t had a period returned since having my child 13 months ago so don’t know how I could be pregnant with no period but still... x
