Spotting for a few days, need reassurance.

I'm 5wks 4 days. I've been sitting for about 3 days now and slight cramping but no more than I would have for a period. I can't sleep and my other symptoms all seem to be normal but I keep panicking over losing the baby.

I had a miscarriage at 17 and felt guilty because I was a bit relieved. Followed by not knowing I was pregnant until around 12 weeks with my oldest son and having light, short periods until I was 5 months along. He was born at just 29wks with no definitive reason as to why from doctors other than possibly stress but no pre-eclampsia. I've had 2 amazing, healthy, comfortable, even "lucky" pregnancy/births since then.

Now I'm freaking out about going through another scary pregnancy and terrified of having another preemie. I know I wouldn't be able to spend as much time with the new baby as I could the first time because I have 3 others who need me now 😢

Just need some reassurance that this could still be a normal and healthy, full term pregnancy.

It's also 4am and I've been up for a few hours so I'm sorry for incorrect spellings or sentences that don't make sense.
