Hello, I found out I was pregnant a week ago and am approximately 4+3 but over the last few days I have been experiencing very intense painful cramps in my pelvis they come on for about 10-15 mins then subside and upto now are happening approx 3-5 times a day, has anyone else experienced this or no what it could be, iv had no bleeding or spotting and aside from a little nausea in a morning and extremely tender breasts and increased hunger no other symptoms, I would appreciate any advice
