Am I imagining it?!

Anna
Hi all, bit of advice needed please. I'm 7 dpo and in our 1st month TTC #1 so a total newbie to all of this. For the last 2 days I been feeling really crampy and uncomfortable and my stomach has a feeling of being 'full up' even though I'm not. Also had lower back aches and been feeling quite nauseous. Does this sound familiar to anyone or am I imagining this? Is it wishful thinking? Perhaps I'm just poorly?! Any thoughts welcome, thanks! Xx
