My period is a week late now. I've had sore breasts, nausea, and I've been absolutely exhausted all the time and last night around 1am I took a cheap store brand  blue dye pregnancy test and got a bfp. This afternoon I took a first response rapid response and got a bfn and tonight I took a clearblue digital and got another negative..idk what to believe...any opinions on this situation? Plan on testing again in the morning but I'm absolutely crushed. I really thought this would be my month.
