Hi all can anyone give me advise please

Rescan in a week (ie at about 35 days after mating).

It might be useful to ellaborate a litte ? How long since mating? How many times was she covered and the timings between? Did you have her progesterone tested? How long had she been in season? Is she a maden bitch? Is the stud proven?

Thanks for replying
Yes this is her first time she came into season on the 9th June her first mating was 10 days after that and then every other day for a total of 3 matings . The stud is well proven stud then her ultrasound was 31 days from the last tie .
