I've had the bar implant inserted in November and didn't have a period till 40 days later, I thought this was normal as the implant messes up your menstrual cycle. For the past almost 2 months I have been experiencing severe abdominal pain that changes to different parts of my abdomen and I also have back pain, these seem to become worse the next day after drinking alcohol. I have no other symptoms. I went to the doctor a month ago and she said it's to do with my diet and the lining of my stomach and gave me a tablet although didn't seek to work, I haven't had my period since my last period but didn't have sex could I be pregnant? Although this seems to feel like something really serious or could it be gas? Has anyone experienced these pains?
