My Last Period Was On 13th Feb

I Was Due On The 15th March But I Havent Come On

But The Last Time I Had Sex Was On The 10th Of Feb Before My Last Period

Is There Anychance I Could Be Pregnant?>

The only sur way to know is to test!!! Sorry if that sounds a little forward, but it is the only way to know for sure!!!

ive took 2 tests on thursday both sed negative

but i still havnt come on

im a week late now

My last period was on Feb 18th, we had sex on Feb 9th..so I was due for my next period March 18th. It is now like 12 days late. Took a home test at about 5 days late and came up neg. I still have no period, cramping bad, sore breasts, feeling nausea throught the day. I dont know I am am very confused?! Anyone have any help or suggestions? I read alot that stress can make the period late, honestly I'm not really stressed though...I am really glad to come across this forum, I know I am not alone. Do you think that either I did the test incorrectly, or I dont have enough HCG?
