Am I in the wrong..?

I'm posting anonymously because I'm a fairly active member, and I don't want this to be used to judge me when I make other posts/comments. I'll try to keep this as short as possible.
I'm at war with myself right now. I'm not sure if my feelings are displaced, justified, or just down right petty. We live with my SO's parents at the moment as we were not financially ready for a baby. (My IUD failed). So we moved out of state to live with them while we finish up our last year of college. 
From the very beginning I didn't feel comfortable with having a baby shower. I felt I didn't deserve one really since this wasn't planned. And I don't believe anyone is responsible to buy anything for our baby. We moved in with my SO's parents in order to save and purchase everything ourselves without the extra bills that come with being on our own. 
His mom insisted I have a shower, because everyone will want to buy things. She helped me make a registry and everything. It was super kind of her! My mom purchased our crib & all that was needed for it. 
Christmas came and my SO's parents bought themselves a stroller/car seat combo. It was very awkward to watch because it was for them. For their use. I wasn't sure if I was allowed to be upset by this so I talked to my mom. She said it was a little odd that they got it for themselves, especially before we even bought one for ourselves. So my mom bought us a stroller/car seat combo. I told her not to, that we could get it but she insisted that she wanted to do it for her grandbaby. 
My SO's other parents (we live with his bio mom & step dad.) bought us a pack n play changer/napper combo. Which was totally unexpected and very much appreciated! So all of the big things were bought & we feel so blessed! Now it's just little things like clothes (my mom & granny went insane crazy with baby clothes and took care of that🙈) baby soap, tub, diapers. Which I chose to cloth diaper after talking to my mom about it and she wanted to get all those for me, soooo that was taken care of too. 
At my baby shower we just had a very small one. (Big crowds give me anxiety.) it was just my SO, myself, his parents, & his uncle/aunt. His parents haven't bought anything for their grandbaby. Which confused me since when making the registry with his mom, she said she wanted to buy it all and how excited she was for the baby and can't wait. She is still super excited which I love. 
But I feel a little sad knowing that I'm days away from my due date and my SO's parents haven't bought a single thing for their grandbaby. It bothers me a bit more because like I said, they bought themselves a stroller that only they can use. & they also bought their son and wife who just got pregnant (she's maybe 14ishweeks) a crib and a stroller/car seat. I just feel like this is odd. I don't know. 
If I'm in the wrong for feeling sad please tell me! I do have bad anxiety and I know I sometimes get too sensitive over things. It just hurts a little. Especially since they want to be at the Hosptial when she's born and to take her out on these little outings and things. Idk.
