12 Days Late

So Af still hasn’t shown up yet. I’m 12 days late and last time I tested was when I was 6 days late and it came back negative. 😭 My periods have always been on time and I’ve never been late before. Last month (March) my period started a whole week early and now I’m almost 2 weeks late... right before my period was suppose to start I felt nauseous, and super bloated. It’s not as bad now, but I sometimes do feel nauseous after that, and get cramps, as well as gassy and bloated. Any advice? I’m hoping I get a BFP but I’ve had so many BFN 😞 Really hoping it’s my month.
