Good morning ladies

So this week Iv been feeling a little different to normal and would like so advice please.

All week I have felt light headed. Had a headache. Eaten a lot more than normal. Feel bloated. Sex drive has being amazing. Nipples have being sore,So I was thinking I may be pregnant, however I tested Tuesday and it was a negative. I’m not due on my period for another 5 days. So I’m thinking is this possible to be pregnant.

Thank you ladies
