15/16 dpo no pms shud I test

I’m 15/16 dpo And iv been late every month the past 3/4 months now so I’m not sure weather to test I don’t want to get my hopes up but iv had no cramping or Sore boobs ore bloating

Iv just had head aches n nausea n can’t really eat a little bit of creamy discharge n a tiny bit of constipation but nothing like normal I don’t get head aches or constipated but never had no pms symptoms before

Should I test or wait a few more days

Just typing this is making me nauseous n anxious
