Late period

Andrea • Fri, Aug 28

I was supposed to get my period last Friday on my husbands birthday. Nothing so far. I tested on Friday and I got a negative. I did have a uti last week. I am so nervous to test.... But I have a wedding tomorrow so I will need to know. I keep on telling myself to wait one more day because AF will probably be here, but she hasn't come yet... I just don't want a BFN.
