Okaii so would like some advice...

I am 6dpo and for the past 2 days i have been feeling nauseous (resulted in me eating mints to stop the feeling). I have a rash on the side of my right breast. And have had a few cranps here and there. Going to the toilet a little bit more (having to get up in the night, which i never had to before)

Apart from that, i haven't had anyother symptoms so i am a little confused as to whether i could be pregnant or if maybe i am just under the weather??

Any opinions/ advice would be appreciated x
