Hi. Just looking for advice. For the past few day Mabey a week I have had trouble sleeping, waking up every couple of hours!! And also have a horrible matallic taste in my mouth. I have irregular periods so not sure when the next is due. My last period was 5 weeks ago. Scared to take a pregnancy test as I had 2 early misscarages last year. Worried about getting my hopes up then for it to be took away once again. How reliable do you think these symptoms are?
