Experiencing first miscarriage

I posted a few days ago that I had finally gotten a bfp at 12 dpo. We were so thrilled. Starting Friday evening (2 days ago) I wiped and noticed some dark brown old blood. I had no cramping and since it was old blood and just a little, I wasn't worried. Yesterday I continued to have it but only a little. I woke up today to heavy brown blood and it has progressed throughout the day to red blood with stringy bits and small pieces. A digital CVS test said pregnant but a CVS blue dye test said negative (there may have been a vvvfl but I gave up looking for it and tossed the test). I'm so sad but I know this happens. My heart goes out to all mamas who have experienced anything similar. Wishing you all sticky baby dust and lots of it 💕
