OK, so I got a BFP on last Saturday. This will be out second child, my daughter if 4. I am so excited but really think the dates are off.
My last period was Dec 24th. If you use that, I am now 9 weeks. Only thing is I tested a week before my positive and it was negative. Anyone ever get a negative at 7 or 8 weeks?? So I'm guessing I ovulated really late, what do you think? My first OB appt isn't till Thursday so I'll go crazy till then!!!

You could get a negative result if there is not enough of the hormone in your urine. Sometimes it takes a while for that to show up.
