Pregnant after miscarriage?

Hi everyone! I just recently got my BFP! I had a miscarriage in July and am pregnant for the first time after. This is my second pregnancy and last time I didn't make it last 6 weeks.  I'm so incredibly nervous about losing this one too. Normally I would talk to my mom and sister about everything but I'm not telling anyone until after the first trimester. It was way too hard to tell everyone we lost the baby. Is anyone else in the same boat or have you been here before? I would love to have a support group for this but didn't find one. Anyone else?
