Pregnant again after misscarriage??

i had a miscarriage last year 6july 2018 at 6weeks pregnant.it was my first pregnancy.i bleed after that from 6july till 15 july and had my "first" period on 8august till 13august.had sex on 14august😅 and on 18august(omg! sorry for the details🤣) and i got pregnant again and now im 26weeks with a healthy baby.according to the app flo it counts my pregnancy starts on 14august.we decide to have sex right after my period because im supposed not be fertile but i guess u are more fertile after a miscarriage. everyone is different. but if u get pregnant too soon after a miscarriage u might get a good lecture from ur nurse and doctor for the first few weeks. i hope this helps.
