Ectopic pregnancy/mtx

Hi guys! On the 23rd of July I found out I was pregnant. Not long after I started having cramps/bleeding and this has not stopped since. Not long after my positive test I ended up in hospital and my levels were low so they expected a miscarriage. As suspected I bled more and more so "I had my miscarriage". My levels however kept rising so after a scan and multiple blood tests an ectopic got established.

I'm getting a MTX injection and I'm so scared 🙈 for anyone who had this, how were your side effects and how long did it last for? Any "advice"? When did you start to feel a little normal again and when was your first period? I already have health anxiety/don't trust my body and grieving the loss of my mum.. I feel like this is tipping me over the edge 😪
