I have had a missed period and am now 5 weeks late. I was sterilised 11years ago. I have some some light vaginal discharge, some stomach swelling, heartburn, back ache and signs of period pains on and off for the last few weeks, I did x2 pregnancy over 1 week ago and both came back with a negative result, but I continue to have these symptoms and slightly swollen breasts. I am a 38 year old female with 3 teenage children.
