Food question

I know this is probably stupid. I took 100mg clomid at the beginning of this cycle, then got the hcg trigger shot on Sunday and had my first IUI on Monday. I've been careful about what I eat. I ate the core of a pineapple because my doctor said it helps with implantation. I'm taking a prenatal, eating protein, 2 servings of full fat dairy per day, limited sugar. Problem is, I splurged and got chocolate cake tonight with dinner. Now I'm nervous that the sugar could inhibit implantation. Thoughts?
