Thank you for your comments . This will be my 2nd child if I truly am pregnant. I have an adorable 3 year old. And hopefully I can give him a little brother -OR- sister .
3weeks is when your officially pregnant
At two weeks pregnant you would be ovulating and conceiving, so no you wouldn't technically be pregnant. I don't think you can detect pregnancy till at least 3-4 weeks. Which would be 1-2 weeks after conceiving.
