Sex in early pregnancy

Naja • Rainbow baby🌈 4/19/21 🥺💗 I love you angel.

Hey guys I’m about 4w 5days and this morning my hubby tried to have sex with me. For some reason when I was getting aroused I had this cramping/ contractions feeling. Is that normal ? I got scared so I ended up telling him I didn’t want to do it until I spoke with my doctor. I feel okay now the cramping stopped and I don’t have any bleeding.
