Pregnant not pregnant

Hey so I previously posted about my symptoms. I have been moody, emotional, craving everything, wanting to eat everything, I have been feeling sick but mostly at night or really late. I can hear and smell everything. There was this table that smelled like dogs and It made me even more sick. I was spotting but there was no period but then my period came on and i was only for legit 3 days. I've been undergoing a lot of changes. I took a test first one said negative then the second was invalid. It was the rite aid brand test. I just wanna know am I cool to drink?
