So this may sound strange, but about 2 weeks ago I woke up certain I was pregnant as sure as the sky is blue. I had no symptoms of pregnancy and my period isn't due for another 5 days. As the weeks of gone on I'm not so sure wether i was just trying to be hopeful and now im trying to minimise disappointment I'm not sure but has anyone had this before and what was the outcome. I'm normally a very realistic person.
