I know I should stay off the internet but I have read so much about possibility of a chemcial pregnancy. I took a few tests on Friday (one day after my period was supposed to start) and they were instantly very positive. But could that still be a chemcial pregnancy? I am now 4 weeks and 4 days with no bleeding yet but when is it safe to feel this is sticking vs chemical. This is my first pregnancy after only a few months of trying so I feel very unprepared to know what is real.
