I was suppose to start my period a week ago and I am late. I've taken test and all BFN.. My lower stomach is bloated but I'm not crampy or anything like I am when AF comes. Usually when I'm around someone on AF it triggers mine but I've been around 2 friends who had AF and it didn't trigger it. I kinda feel sharp pains in my lower stomach like I did when pregnant with my daughter. Only "symptom" I have had is some nausea. I don't even have an increase in CM... I did a few days ago but none now. I also have been going to the bathroom ALOT.

What could be causing me to be late in your lady's opinions and from experience. Please respond if you can I'm really nervous.
