Any advice?😳

So peeps basically, the past couple of days/night I've felt so sick, tired and just really not energetic which isn't good as I work with children 😐 especially at night time, I dont wanna eat, constantly bloated and during the day I have to suck on sherbet lemons to stop feeling so sick 😂🤭 I'm currently only 5dpo and have also been experiencing extreme cramps the past couple of days but I don't wanna test cos I've got a feeling its gonna be BFN...😶 what could be wrong with me?! Anyone?!
