need some thoughts...

first time using app. and really using it daily. now here's my question. I have hyperthyroidism and currently have a upper respiratory virus ( getting better tho.) ANYWAYS.... I don't know if I'm PMSing or I'm finally pos preg. as you can see from the charts. I'm supposed to be due the 18th But... my nipples are VERY sensitive to the point that accidently grazed my corner of the counter and yelped in pain. also I'm seeing like crazy. tired but not sleeping much. wake up and must rush to bathroom go pee. ladies, any ideas?
