So when I went to my appointment I was supposed to be 10 weeks, due date around April 3ish but in reality they said I'm only 6 weeks 2 days (this was on Friday). I'm so confused on how I ovulated that late. My period was on June 28 for five days. I used the ovulation strips and got three positive tests on random days but the most prominent one was on July 18. At my ultrasound they said there's two sacs, one fetal pole but could hear no heartbeats. Is this normal? I really don't even know what to think. I go back this Friday the 15th and I'm honestly expecting the worse even though I'm trying to not worry. Any advice would be appreciated.

Edit:: my new due date is supposed to be may 2.. almost a whole month off 🙄
