I'm a little sad

O`dessha💉💊
Me and my boyfriend are ttc I've had sex during my fertile window and I used ovulation kits. I've been counting down the days until I could test. But, Today I started spotting😥. 3-4 days leading up to the spotting my breast has been very sensitive. To the point I have to sleep in a bra at night. I never had issues with tender breast before. I'm hoping it's just implementation bleeding that I'm experiencing.
