Late period

Kressian

Heyyy!!! Today marks being two days late for my period and I always start the same day every month like clockwork.. I took a test this morning when I woke up but it was negative. My nipples are sore and my lower stomach on my sides are hurting/cramping sort of which I’ve never experienced before. Could it still be too early for a positive to show up or do y’all think it could be my period trying to start???
