Monday I found out I was pregnant from the emergency room & today I at my first check up another, both were positive. Lol according to my last period I am about 4 weeks & 2 days pregnant today. The only symptoms I am having are my boobs are super sore and I had been cramping on my right side most of the day yesterday. However, today I just have the same side ache. Has anyone had this? This is my first pregnancy and I was told my DR couldn't see me until I am 8 weeks. I'm worried about an ectopic pregnancy with the side cramps. Please help if possible.
