First signs, could it be?!

I’m 7dpo and my nips hurt at 2dpo and just got worse...... now they feel like when you catch your fresh tb injection...... an oooooo ouch every time they are touched. Boobs sore and tingles..... had a visual migraine followed by an actual one yesterday, I’ve had to be in bed by 8:30pm or I might sleep where I’m standing..... also been eating tuna and bbq beef hoola hoops for lunch and I get soooo amazed at how good that tastes..... off some foods..... sooooo thirsty no water will help, cotton mouth and alittle nausea around 11:30 each day. 3 days till testing
