4 weeks 3 days

charlotte • TTC 5years due with my first rainbow 9/9/2020

Hiya might be a silly question but I've been getting a bit of cramping like wiered pains not quite period cramps pains and they last all of 5 seconds on my left side I was told this was normal by family so I've been trying to ignore it but today at 4 weeks 3 days I've had the tiniest bit of brown discharge is it normal ?? It's Friday so I can ring the doctors ...
