Cramps- lower back pain

Danielle • Sun, Apr 19 • Happy Mama of baby girl Fiona

Hey guys... This is my second time being pregnant.... First one ended up being a molar pregnancy. I am 5 weeks now and once in awhile I have lower back pain like when I am getting my period. Of course when I read on the internet, it says it's a sign of miscarriage. If I end up losing another pregnancy, I will be so upset. Anyone else experience this ???
