I had a miscarriage at 7

I had a miscarriage at 7.5 weeks on August 2nd. My period predictions have been off a few days since I started my cycle again in the end of September beginning of October....usually by 2 days. I was due on the 13th and haven’t gotten it and thought it was probably due to the crazy amount of stress I’ve had the last few weeks. Nervously I bought 2 tests today and it came up positive within 3 seconds. I’m so excited but so nervous at the same time...I just can’t emotionally hack another miscarriage. I’m praying this is my rainbow baby!
