honestly i didnt know that my odd, different PMS symptoms were actually early pregnancy symptoms. i would notice that not only did i have an increase of cm, but my cm consistency would change all throughout the day. i would think that i was ovulating over and over again because one morning it would be ewcm and then an hour later the same morning, thin and watery. and then later that day, creamy. i noticed it was like this around the time i got my bfp at 8 dpo and it continued until i was about 6 weeks along. i can barely remember the exact time it all started and ended but it was definitely a TON of cm, and the consistency was NOT EVER the same throughout the day everyday.
i didnt ever check my cervix or even believe i was pregnant but i took a test at 8 dpo because my boyfriend at the time (now fiancee) said he knew i was from how i was acting. plus i was sneezing everyday with swollen breasts since dpo 1.
