Advice or support most welcome!!

I feel lost and not sure where to turn!! I don’t want to be one of those women who contact the doctor for everything! I’ve had 2 miscarriage my most recent last year, I found out On sat I’m about 5 weeks pregnant so as you can imagine I worrying about any little thing as I really want this pregnancy to go well.

Well on Monday my partner and I had sex and I started bleeding, not a lot just spotting it was light red/pink and it stopped within half an hour. I’ve been to the doctor who has referred me to the early pregnancy unit so just waiting to hear back. I’ve been experiencing some mild to moderate back pain which since yesterday has seemed constant but has eased of a little and seems to be worse when I’m sat up.

Should I be concerned or is this normal!
