We had a miscarriage 1.5 years ago and haven't been pregnant since. I tested every day and bought a new batch of first response tests which appeared almost negative. I also had an extra Clear Blue but that was pretty positive. This was at 4 weeks and 3 days. After seeing the first response, I assumed I was having a chemical. I cried for much of the night on Thursday and Friday morning got a call from the nurse that labs looked great, HCG tripled. I'm so nervous. She said the urine test could've had a bad batch of dye. I'm still so worried. Anyone ever experience something like this?
