so my fiance and i have been together 5 years, never used protection. i had a super early miscarriage within the year. we don't always have sex all the time and sometimes he doesn't finish in me. we have tried a few times i dont temp or anything i just go by my period and when i should be ovulating and then have sex and do the legs in the air and such. we've tried actively for a few months here and there maybe like twice and then usually just quit and say it will happen eventually. and sometimes like when its hot outside we don't have sex much. should i be worried?
