are these symptoms possible??

Hi ladies, is it at all possible to be tired, headachy, food tastes a wee less good, a bit sick and dizzy at 2 dpo ? as a sign of pregnancy?
I'm just wondering cause if it isn't then i'm brushing it off as something else ..

and I just now keep having this feeling in my stomach that something has changed .. like idk .. maybe i'm just going mad!

but I also just started meds for depression (which are ok for pregnancy btw) so maybe it's those? :/

 

thanks
