potentially 6th pregnancy in 13 months

Jenny
Hi ladies,
I ovulated super early this month and got a VFL at 8DPO getting slightly darker by 9. But still, VFL. I am about 6 days from my period(28 day cycle). Seeing as tho I have had 5 pregnancies over the course of a year all end before 6.5 weeks, at my last pap my doc told me to come in when I have my next positive test and she will test me in the office and prescribe progesterone.
The problem is, I leave this Saturday for a week holiday. So I would have to see the doc in 2 days. Is my pregnancy really going to register on their tests? I think they first will do a urine test and if that is positive a blood test. Worried it'll turn out negative and they'll send me away.
