I had similar pains at 5 weeks and got very scared I had an ectopic. Turns out it was only round ligament pain which is very normal. Look into it and see if your symptoms match. Good luck!
I called the OB and they said I'm on pelvic rest for the time being. And to rest today. They don't want to see me until my appt, which isn't till Sept. 10th. I kinda think that's weird.
I think you need to go to see your GP, or to hospital. They say if u have one-sided pain, its a sign of a ectopic pregnancy, which is dangerous if left untreated. Do you have any shoulder pain?
You should try and get in to see a doctor. I am about a day behind you and I'm experiencing different things. I'm not sure if the jet ski would have anything to do with it. I would said it might be the sex. The doctor did tell me to stop having sex until I can be examined further and possibly until I get out of 12 weeks.
