I am not on birth control and my period is 9/10days late possibly more 
We dtd on day 9 on my cycle but it's been a hectic month and that was the last time exactly 4 weeks ago today...now we didn't use protection however he 'pulled out' ( I feel like such a stupid teenager ATM writhing that I should know better)
I did a test yesterday it was negative I feel fine apart from the odd phantom cramp as there is no sign of this period. I don't think I am pregnant or am I kidding myself
