Potty training trenches

PLSSS HELPP !!!! My 10 week old Goldendoodle has been doing great with crate training and potty training on a fresh patch of grass in her play pen but every time we take her out of the pen to train or play she pees or pops on my carpets 😭 only my carpets. I have a timer on my phone set for 30 mins to take her out and she’ll do good for a couple of days with the 30 mins and then randomly will pee before the 30 mins are up even though she just used it outside. My trainer said once she is doing good every 30 mins after a couple days bump it by 15 mins and if she has a accident go back to 30 mins . I have done everything he’s told us to do from leashing her to me and we don’t use puppy pads in her pen. She is doing good in her crate but we still wake up at 2:30-3:00 am for a potty break at night which we don’t mind but I thought she was doing good and recently discovered that she has been peeing on her blanket so we removed that and just left her snuggle puppy. But now she’s also peeing on that so should I go back to waking her up at 12 AM and 4am like we used to or try to get her to hold her bladder till 2:30-3:00 when she normally barks and wakes me up according to my trainer we shouldn’t wake her up during her sleep like we wouldn’t with a baby. just need some recommendation some new advice because his really isn’t working. Also, she eats 6am- 10am- 4pm three times a day. Last water is at 7pm. Last restroom break is at 9am. Wakes at 2:30/3:00 am potty break and 7:00am again. Rest of the restroom breaks are a bit more random. I only take her out of her Crate to use the restroom. If I hear her restroom cry I let her calm down first, of course before I take her out. Also, I took her out like after eating and after napping she does amazing when in the playpen it’s just when she’s let out. she is confined to the living room when she’s out so it’s not like she’s roaming the whole house and then I’ve got so much contradicting information to let her finish going potty so I won’t spook her and so she won’t have bad association with using the restroom. And other to pick her up immediately but then it’s a trail of pee leading out. THE PEE WONT STOP
