Massage chair while Ttc?

This may seem really stupid to ask, but today was my most likely day to conceive. We BD and then a few hours later I sat in my massage chair and it really shook me around a lot. I didn’t even think about it, but could it prevent me from implanting or fertilization? It was 4 hours after BDing. I’m probably just being paranoid, but I really hope I didn’t screw up my chance for pregnancy. I just have anxiety about it now when I’m sure I shouldn’t.
