Pregnant after a loss 🌈

I had a miscarriage last month, I didn’t think I would be pregnant this soon as I tested a week ago and it was negative. I’m so worried but so happy, I’ve never gotten tests this dark this soon (about 12 dpo) praying this one sticks 🤞🏼💗 I have had light brown spotting for about a week which is really worrying me but the tests are getting darker and much darker than last time.
