Unsure (sceptic)

Hey this is really crazy but been trying for 4 years me and my partner when to see a medium and she said are you trying blah I said yeah she says I'm not spose to predict but watch this space April/ March it shall be here ... now according to glow I be about 5 weeks if I am pregnant and few other sites say I'm bout 3_4 weeks .. I'm worried and hopefully I am but would it be too early to test I'm not sure .... getting odd few cramps twinges here and there but nothing else amongst all this I ended up with bells palsy and in steroids about 5 days ago which is about day or 2 after seeing the medium ... am I being crazy ???
