Early pregnancy can someone help?

[20mumy13]

So I posted on here last week now things have changed. So I'm still getting the cramping in my abdomen and lower back ... no bleeding thank the Lord! I'm currently about 5 weeks! I previously had a miscarriage 2 months ago and obviously now I'm pregnant again and petrified of it happening again! I also have a 3 year old and I don't really remember early pregnancy with him to well! So like I say I'm still experiencing some cramping in abdomen and lower back pain. Some is mild and some actually hurts (rarely) I've had what feels like stretching which actually woke me up and again I've had no bleeding thankfully. But .... MY boobs dont seem to hurt that much any more my nipple still feel a little sensitive if you touch them but that's it. I still am tired and hungry and my moods change etc ... but obviously I'm worried due to my past. Has anyone else experienced this??
