Week late...

Madison

Question, I’m a week late and I’ve taken numerous test and all are negative. I look clearblue tests at about 9dpo and there were faint lines but then I took a FRER and it was negative. I’ve been reading a lot that clear blues can’t be trusted. But I don’t have any signs my period is coming. Some days my boobs hurt really bad and I get super nauseous that’s it. Any ideas what could be going on?
