Worried because of past miscarriages

I took a test on Monday and it shows positive, yay! But I’m still hesitant on getting excited with my history of miscarriages or “chemical pregnancies”.

So this one is from Monday:

You can see the line but it’s faint. In the past when I have an early miscarriage the line fades away within a couple of days.

I just tested right now, it’s Thursday.

I’m excited to actually see the line get darker but don’t want to get happy too soon... I just don’t want the heart break worse if something happens.

I have gotten labs done and need to repeat them tomorrow. Hopefully all the number are double like they’re supposed to!! Keep me in your thoughts 🤞🏻❤️
