Really early days for me (5 weeks) but I have some symptoms but not all the time and not every day. Yesterday I had metallic taste. Day before I felt nauseous when I woke up but didn't yesterday or today. Every day or so I get a boob twinge. And when I got up today I got a twinge in my lower tummy. But nothing consistent - is that normal? (Can you tell this is my first and I am worried?)
