I'm 8 days late on my period and I'm usually on time. Me and my husband had sex everyday of my ovulation, however this is our first attempt. I keep having symptom of my period but nothing. Not to mention I've been sooo moody. I took a test at say however id only b 21/2 weeks do you think I shld b able to get a positive if I'm getting symptoms
