any thoughts?

so for the last few days/nights I have had to go to the bathroom way more which isn't normal. I also have been way more hungry then usual and been feeling super nauseas. I have three different apps and are all telling me my monthly friend will be here anywhere from October 6th to the 10th. I took a test today and it was negative. my husband and I have been ttc for 7 months. and about a week ago I had some slight cramping. just trying to get some advice or no if anyone else has experienced this? any thoughts would be great:) thank you!
