I've been trying to fall pregnant for 5 months now. This month, as with every month, I got too anxious to wait for the first missed day. I was due to get my period today, and tested yesterday with a -ve reading. It's 10:00pm now and I still havn't got my period. Since taking out my implant 5 months ago it's always come on the 18th of every month. I've got another test, but I promised my husband I'd wait until at least tomorow before I do another test. Seen as I got a -ve yesterday, is there any chance it might come up +ve tomorow?
