ok mom's I was supposed to start last Thursday and I still have no signs. I've taken 4 test and all negative. I was thinking about waiting it out the week and call my doctor Monday for a blood test. do you guys think that's a good idea? I have had some signs of pregnancy like extra cm and bad heartburn and cramping on one side and loss of appetite. also the people I babysit for their dog will not leave me alone and she hates people.
