late period, dont think i could be pregnant

mackenzie

ladies, before i go on to say what i need advice/insight on, i plan to go see my dr and get a medical exam. i had a miscarriage this past January and ever since my period has been somewhat irregular. however i will say that the times it was off in the past, i had been having unprotected sex and thought it could have been a possibility i was pregnant again when i would be late. this time tho my period is almost a month late and i haven’t slept with anyone since august 18th. i had my period in september starting on the 13th and never got it in october. i’m starting to get concerned that i may have some kind of issue or something. i have heard that some women have a full cycle right after conceiving so they won’t realize they are pregnant until they miss their next period. is that accurate? i cant seem to find an answer online and i dont want to ask my friends or family because i don’t want to get them excited or worried. please if any of you have insight, i’m all ears.
