My Deer Head Chihuahua accidentally mated 34 days ago. She is 4lbs. She got an ultrasound at 28 days and the vet said he didn't see anything but he also said its possible it was missed because she is so small. She's been cleaning herself a lot, although I don't know if its more then usual. Im home now because of this virus so I see her more. She isn't showing at all, her nipples are pokey, maybe a little bigger then usual but haven't grown in the past couple weeks. I looked up how to palpate a belly and I have been doing that every day the past 2 weeks and just in the last couple days I have been able to feel a small solid thing in the middle of her abdomen when I push in. Is it possible she is pregnant even tho she isn't showing at day 34, if she isn't, what am I feeling in her belly that I am pretty confident wasn't there before? I really am not looking for opinions on the whole situation, I am just asking if there is a possibility that she is pregnant without showing at day 34. Thank you!
