?Umbilicus hernia

I am 10 weeks preg. Lately i realised there is a protusion over my abdomen and when i press it, it feels squishy (very intestine like). Whenever i exert myself (doing mopping or lifting my 20month old son) i feel like something in me has sunk or like something dropped further down. I am wondering if anyone has ever experienced anything like this. I dont want to go to the OnG clinic as my bowel patterns are still ok.
