Super confused

Ok ladies I’m so confused need help so my period was supposed to start on 15 and nothing so on the 16 I noticed like pink when I wiped and I hate horrible nausea so I tested and had a positive test again later in the day another positive on a different brand . Well today In the morning I saw blood again only when I wipe but it’s lasted longer I have mild cramping I used a pad but it’s not soaking it doesn’t feel like my normal period and the nausea is worse today so my question is am I pregnant or late period and is this implantation.
