I am 20 years old and 15 days late. I have a pretty regular AF. I don't know what to do and its driving me crazy. My finance and I have been trying to conceive for about 7 months and it would be a wonderful blessing if I am. I am going to take another test 2morrow but if that one comes up negative I don't know if I should wait until my next period is due or if I should go ahead and get a blood test done. I have been reading other posts and I have found out that some women don't get a positive result even with a blood test until the are 6-8 weeks pregnant so I'm confused. I am having all the symptoms like nausea, bloating, slight cramping, tired, hungry much more often than normal, and headaches. Please help...advice would be greatly appreciated. Thanks 8-|
