Literally ran away from gift 🙈

Yesterday we we're over at my in-laws house to tell my husband's grandmother that we are pregnant. My SIL and BIL were also there with their son. After we told grandma, we all went outside for a moment and as we were walking back in my SIL got a bag out of her car and said "I got you something, can I give it to y'all now?" and I said "If it's baby stuff wait until the 2nd trimester like we talked about!" She said it was baby stuff and then insisted on giving it to us. I panicked and said "No I want to wait until the 2nd trimester, I don't want to jinx anything!" and literally ran inside the house, leaving my poor husband there to accept the gift even though he wanted to wait as well. I realize my reaction was not ideal but I just PANICKED. We haven't bought ANYTHING baby related and I have had many conversations with my SIL about how we want everyone to wait to buy things until I’m in the 2nd trimester.

A little back story, we have been trying for 2 years and finally did IVF in July. Praise God it worked and I am 9+weeks pregnant. We are so grateful and excited to be pregnant but also so scared we are going to mess this up. I tried to explain my reasoning for how I'm feeling/wanting to wait to get baby stuff last night to my SIL but her response was that now that I'm pregnant my situation is no different than any other pregnant woman and I need to get over the fact that we had to do fertility treatments. Basically, she thinks I should be acting the same way she acted during her pregnancy (they got pregnant the 1st month they tried). I obviously apologized for not accepting the gift, I know I was wrong in that regard, and we opened the gift last night even though we weren't really ready to. We felt pressured into it and we weren't ready.

Mostly I'm feeling confused. Like my feelings about my pregnancy aren't normal. I'm also a bit angry because I had told her no baby stuff yet and she kind of forced it on me and ambushed me with it. Plus, I feel lonely in the sense that I tried to explain how I feel but was told I need to get over it.

So I guess my question is, is it normal to feel a little different about a pregnancy after infertility?

Again, we are SUPER excited and grateful but also really scared we are going to mess this up, like it's too good to be true.
