I’m 8 weeks 2 days. I have light spotting just now. I’ve had some backache when walking as I find my back is stiff and clicking about at times. Yesterday I had a tiny amount of pink discharge and a dull ache in my right side. Almost felt like pressure. I was due my 2nd missed period yesterday. I’m seeing my midwife for the first time in 3 days time for my usual first appointment. Yesterday I did lift a heavy bottle of water and felt uncomfortable so I dropped the bottle immediately. This is my first ever pregnancy. Could it be implantation or the placenta taking over from the yolk sac? Or normal because my period is actually due this time? I’m symptom watching and anxious at times. What’s the difference between normal cramping, back pain, normal spotting and more serious issues like miscarriage? Thanks
