Cramps... no flow.. sore boobs.. HELP

Okay so last period started January 16th, pretty sure I ovulated 2 weeks ago from today’s date(my periods are usually inconsistent so I could be wrong) I’ve taken two p.tests the most recent being Saturday- was negative.

Last three days I’ve been having cramping and super sore breasts... we’ve been trying to get pregnant and this would be our first.. so far no flow and just cramps which I know just be period symptoms.. Help please we want a baby so badly and I’m stressing over here..
