What's Going on?? Freaking out inside!!

JoAnna

I am 5 weeks late, I am on day 66! The week I was suppose to start, i woke up went to pee whiped and there was a very light light pink on toliet paper. I thought oh dang about to start, but never did. I took a dollar tree pregnancy test on Sunday a week ago and it was negative. I have never went this late but only once and I was pregnant with my first(9 years ago). Here is the kicker my husband is infertile(the Dr say) so we don't do nothing to prevent we just hope and pray. What do y'all think is going on, what do I need to do?? help!!!
