unstoppable hunger very early on!!

Elle
Hello there! I'm exactly 6 weeks today and starting about a week ago, I started experiencing hunger pains. They have gone downright out of control within the past 3 days and today is just outrageous. Nothing can satisfy me. I ate cereal and fruit, hungry 30 mins later (literally painfully hungry), just ate a mini flatbread sandwich (it literally did nothing for me!) the hunger is waking me up in the middle of the night! I've been keeping apples and grapes at my bedside. To make matters worse,  Actual cooked meals are nearly intolerable. I immediately get this overall crummy unsettled feeling after eating. The only thing that doesn't make me sick are fruits, salads, cereal, crackers and sabdwiches. I'm only 6 weeks, is this normal!???
