symptoms disappeared

Soo since being 5 weeks pregnancy I have felt awful! Nautious, tired, cranky and just generally not myself. But now since Saturday (i was 10 weeks 1 day) I have felt pretty great and have done since. I haven't felt tired or sick or cranky. The only thing I'm feeling is my boobs are still sore and my appetite isn't amazing but apart from that my symptoms have gone 😳 has anyone else had this? I'm freaking out as I feel, could it be the start of a miscarriage? Or just my pregnancy getting easier as i'm further along. I've had no cramps or spotting? Please tell me your experiences, first time mother freaking out ❤
