I had a miscarriage 5 weeks ago at 7 weeks, hcg returned to 0 and we tried again, got a positive result on Saturday at 10DPO, tested again at 11DPO with no change in the line, then I did one today at lunchtime at 12DPO and it is very much lighter. Is this a chemical pregnancy? My back hurts so much and I feel like it’s going into my groin and it’s reminding me of my miscarriage. I’m so devastated and I feel like something is wrong with me. Should I retest in the morning? Top is 10DPO middle 11DPO bottom is today 12DPO.
