Worried?

Hello. This would be my 2nd pregnancy. I’m 6w4d. My 1st pregnancy ended in a miscarriage. I’ve been spotting today. And had having cramps. But not cramps as bad as when I miscarried last time. They’re just faint cramps. I’ve also been feeling like Im about to start my period. You that weird feeling you get right before you start. I just want to know if that’s normal at all. I e read about it and it said it was. But I just need conformation from people who have had children, I know that sounds silly. But I’m just terrified if it’s not normal because I don’t want this pregnancy to end last my last because Me and my fiancé would be absolutely devastated and crushed and so many other things. And I just want to give him a healthy baby. I’m just very concerned. 🙁🙁
