Pregnant after miscarriage

I had a miscarriage in June and I am still so devastated by it, had my period in July and wasnt thinking I’d get pregnant again so fast,but found out I’m pregnant again. I’m terrified I’ll lose this baby as well, every cramp I get panicked and overthink and I’ve probably taken a thousand tests. Did anyone have a healthy pregnancy so soon after a miscarriage. Or does it increase your risk of another miscarriage. That was my first one and I have a three year old son
