Long story 😫 but I've got everything crossed for everyone on this page 🤞🏼🌈

I had a mc 17th of July, stopped bleeding a week to ten days later and started to ttc again straight away. This past week I've had slight symptoms back, I've done several pregnancy test since Monday with very very faint lines. Which are visible but only just (don't know if I'm looking to hard) but they're not getting darker. I did get a negative test before I started ttc again btw. I am booked for bloods on Friday but has anyone had similar situation? I'm going crazy my minds in overdrive!
