Due date changed

Melody
Went today just to be reassured we actually had a baby .WE BLESS God but we are only 6wks and 1 day..instand of 8 weeks.but with my last period I should be 8 weeks but the utersound is measuring me at 6 wk 1 day. Ob. Said I probably ovuated a second time in month but I didn't conceive until the day before my Aug.period was due. Had some spotting so with my age he is doing a complete hormone level test on me to make sure my hormones are where they are supposed to be. Said i might have to take Progesterone with the this pregnancy. We did see the heartbeat already said it was early. Praying our little on will be a fighter like her sister and brother
