i'm 35 y/o. this is my second pregnancy. the first one was tragic. I mc'd when I 21. now 14 yrs later, I pregnant again. very joyful, but still concerned. morning sickness lasts 2 weeks. went to the doctor 11/21. transvag. u/s. the same day I was bleeding for a week and 3 days. moderate cramping, but passing gas a lot. everything was fine on my next doctors visit. she told me not to be alarmed about the implantation bleeding, it was normal. but i'm still worried that's why I didn't want to go through that again in my 20's. now i'm in my mid 30's, it's totally different. what could it be? am I still early? is my estrogen level is down or what? i'm going crazy here!
