I am 2 days away from starting my period, with 14 months of TTC under wraps, 2 chemical pregnancies*

So this afternoon I took a test and got a faint positive! I was so excited so I ran to the store to buy more tests for the next few days. I’ve been peeing so often lately, so as per usual, I just got up to use the bathroom. After I wiped I got a really light pink vaginal discharge. I know that is a sign that I could be starting soon, but I also got a faint line on a test I took today. I’ve read that it can be spotting from the uterine wall making adjustments for baby, but I’m so scared that I’m losing this. Has anyone had spotting this close to their predicted period and still gotten a negative test?

Help!

Also- My 2 chemical pregnancies I mentioned above, I had no spotting. I got clear positive tests and then later started my period, and had negative blood work at OBGYN on the next day, for both pregnancies.
