So I'm currently 13 dpo my app says I'm supposed to start tomorrow have been having period like cramps mainly on my left side and silently in my lower back I dont cramp before starting my period normally I just get very irritable the day before and I havent had any signs yet i want to take a test i just feel like it's still kinda early should I wait a few more day or do on in the morning ?

Last night when i went to the bathroom i did have a very little pinky discharge ones but that was it

If I possibly am pregnant this would be my first
