Hey, everyone. I skipped my period last month (first time that ever happened), but this month on 20th October I had a dip in my BBT. There was also a dip on October 9th then it increased until 20th where it dipped and it increased after again. Additionally, yesterday and today, discharge has been pink then brown (the pink had tiny streaks of stringy material). Cramps on my right side started on the 18th & today I have a bit of nausea. I have been taking OPKs over the last week and they were so faint, hence negative which confused me because I should have been ovulating, especially with the CM I was having. Could this be implantation? Please, help.
