On and off stomach ache.

Hi ladies, this is my second child my first was 5 years ago so I can't really remember lol. I'm 4w 5days and for the last week I have had more or less constant belly ache, it's not a pain it's just aching with the odd cramp/twinge... No bleeding thank god! Is anyone else experiencing this feeling as its starting to make me worry 😩
