Late period

Denise

Hello I just need some advice what to do. Well I haven’t got my period, it’s 15 days late, I did took couple pregnancy test and they all came out negative but I am very bloated and I have soreness on my nipples. Some fatigue too. Beginning of November I was spotting and I thought my period was here and it wasn’t. 🙁 what y’all think? Did anyone experience this?
