Possibly pregnant?

We have a mare that we have been struggling to get pregnant for about 3 years now. Last year she had a retained follicle and finally ovulated last winter. She had many follicles this spring so we used regulate and lutalyse at the beginning of the year. First cycle and she did not get pregnant, second time she came in she still had multiple follicles and again didn't catch. Took her in for round 3 and she had 1 follicle on each side, and both were 35 mm. She accepted the stallion for over a week still and we bred her until she was out. Took her in around 14 days and vet said she felt pregnant but couldn't find anything. We teased her and she never showed she was back in heat. Took her in today and vet says not pregnant, and that she has a 40 mm follicle and should be ready to start breeding. So we bring her home and try to breed her and she will have nothing to do with the stallion. Striking, squealing, kicking, trying to leave despite restraints etc. The vet says to give her lutalyse to bring her in. My real question here is - can she be pregnant and have a 40mm follicle?

A couple other things of note - she is a maiden, 11 years old. OTTB 16.2 hh and we are breeding her to a 12.2 hh welsh pony. The vet thinks the stallion isn't able to reach the cervix so we are going to try AI (despite that we have done this size cross before with no issues). If anyone has experience and help with the size difference that would be great too. Also a new stallion and is around 17 years old so we are going to test his fertility. He has had foals before but not sure how long ago.

For sake of playing devils advocate, how experienced is your Vet? Is it possible the 'follicle' the Vet is seeing is actually that blessed 'blob' we all long for each breeding season?

Do you know what size follicle, roughly, she was ovulating on? Perhaps she's just not quite 'ready' yet.. would be worth checking her daily for a few days just in case, IMO.

On the flip side, I have an OTTB Broodmare who has cycled via ultrasound like clock work, ovulated consistently, but won't tease for the stallion........ talk about a frustrating, expensive year.. and an 'empty' mare!
