Very excited!!!... now what??

I took a pregnancy test this morning, and for the first time since my chemical pregnancy in July. I have gotten a line!!! It’s so very faint though. You can only make it out as a pink thick line when I put some light on it (not behind it for those who want to jump down my neck). I’m so nervous I’m going to have another chemical! How do people get through this again? And should I tell my partner now or wait until the lines dark enough I can actually take a photo hahah!
