Pregnant after a miscarriage

Courtney

Hi ladies, can someone help me? I’ve just found out I’m pregnant, I got a positive test at 10dpo, I had a miscarriage on the 5th of February, took ovulation tests and found out I was ovulating around 26/27/28th of feb, (one of those days) so took 3 weeks for me to ovulate from having the miscarriage. how will they work out how far along I am?
