I went through one miscarriage with my fiance and so we kept TTC then it showed up pregnant. im so excited but I'm also terrified of it happening again. i know i just need to relax it's just so hard.
You might be really early still. My sis in laws levels were low until she hit 6 weeks. The best thing to do is just keep calm. There's nothing you can do but just wait sweetie. Keep a positive mine though, that can make all the difference in the world. I'm 25 weeks 5 days and I still get really bad cramps. It could be normal! =)
