Pregnant and pink spotting after BD

Hina

Hi All, not sure where else to ask. I am 5 wks and 2 days pregnant and we had BD today since finding out I am pregnant that was 12 days ago. After BD when I wiped there was a little pink spotting on the tissue paper. I and my husband are scared to death now in case something happened to the baby because of BD. I have been monitoring and no spotting since then but mild cramps. Is it something to worry about or is it normal?
