and now I am speculating when to drive to the stud??

This is my girls prog.levels:
Saw blood  Sat. 19/1.
First prog test   Fri. 25/1 was  0,2 ng.
Wednesday   30/1 :               1,7 ng. 
Friday 1/3         :                   1,3 ng ( test made different animalclinic).
Today it was     :                   2,7 ng

We are talking about  natural breedings and  would rather be a bit to early  than to late. (My girl  did not concieve at prog. level 16,2ng and heat was nearly over.)
I have 3 hours drive and will be staying a couple of nights .  Thinking of perhaps drive tomorrow and new prog. test Thursday?  What do you think?? Thankful for answers
 

I wouldn't leave the next test till Thursday. I would drive down domorrow and test Wed.
Once they start to rise it often goes up fast. May double each day now.

If you are going to the stud why test again? See how they react together, if no one is interested then test again.

Hotel is booked from tomorrow until Friday.

Just talked with the stud-owner. The oldest male in the pack has not been wrong yet when to "snif out" which girl is ready for breeding.

Think I am going to trust that male to. If no interest the next couple of days , new test willbe taken.

Thank you both for  good advices!!!
