I have a 2.5 year old and a lot of the symptoms i'm having I had with her. With her I tested 5 days later than when AF was due. Anyways, today I took the First Response test and it came back neg. Suppose to be able to tell result 6 days before missed period. I have sore/tender boobs, waves of nausea and lightheadedness started last night...Thoughts?
