Gut feeling-miscarriage

An

I’m currently 7.5 weeks pregnant. I’ve already seen the fetal heartbeat at 5 and at 6 weeks. However, I keep having a gut feeling that I will miscarry this one (I just turned 41). I just can’t shake it. This will be baby #5 for me so statistically I feel like my odds are good, but this pregnancy just doesn’t feel “right” so far. Anyone else have the same feeling in early pregnancy?
