Could I have advice or help please

Hello, me and my partner having been trying for a baby for the last 9 months and the last couple of weeks I've been feeling not myself I've lost my appetite completely like I can only eat foods I fancy or really want I get full after a couple of mouthfulls, I'm feeling a lot more tired, I'm having a clear discharge from my virginal area, my moods seem up and down, some smells of food make me feel sick, I've been having some cramps in my stomach. I was just wanting to know if you could tell me what it be might.
