pregnant before first period after miscarriage


I’m (estimated) 6 weeks pregnant with my rainbow and feeling super yucky already- way different then my last pregnancy. My OB has me coming in every 2 weeks until the 2nd trimester to measure HCG levels and all looks good so far, I’ll know more when I have my ultrasound next week. My symptoms have me really nervous, as this feels so different from before. I’m lightheaded and have all day/night nausea (not much puking though thankfully). I just want everything to be ok, and every little pain and twinge has me in tears, as my missed miscarriage last time really has me questioning my mother’s intuition to know that something is wrong 😢
