I hope that's all it is. I am waiting for my ultrasound now. Hopefully they will be able to see something this early :)
I had that to on my left side. I was worried it was etopic, so I went to the ER. Dr said I had a cyst on my ovary and it was normal to have it. The ovary releases extra hormones and it can cause a cyst. As long as there's no bleeding and the pain doesn't become severe, you should be fine.
When I first found out I was pregnant I had the same pains. I was scared it was ectopic, but it just turned out to be round ligament pain. I'm 16 weeks and still get the pains but now I get them on both sides. From what i understand I'm going to continue to have them as long as I'm pregnant. I personally I just kept an eye out for bleeding and other symptoms of infection and hemorrhage. If you're really worried call your doctor and see if they can get you in early to check.
I am 7 weeks and have felt full aches, pulls and cramps. From what I've read it's normal. I have a viability scan on Friday so feeling excited and nervous.
