Triphasic chart??

Danielle

This is my second month temp charting, my first month was a disaster I think because I had a crappy thermometer. And this is our 5th month ttc! I think this is a triphasic chart and I don't want to get my hopes up yet again but read it can be a sign of pregnancy!! Have any of you had this with a BFP?! Also- am I losing it and this is actually not a triphasic chart?? Help a sista out! 🙏🏻🙏🏻🙏🏻
