I'm 7dpo and always said I wasn't going to be a person who over analyzed everything as we haven't been ttc very long (3 months). However, I immediately started having creamy cm after ovulation and it has continued. It's enough to be obvious and is unusual for me as I usually get fairly dry leading up to my period. Yesterday I had lower back pain in the morning and mild cramping that went away after an hour or so. Then in the evening I was doing dishes/cleaning up the kitchen and was extremely sensitive to smells, so much so that I gagged several times and had to stop. Now this morning I feel unusually nauseous and am having trouble finishing my morning shake. Am I overanalyzing or are these symptoms of implantation? It seems too early for these to be pregnancy symptoms, but it's all very odd for me. My period is due in 4 days.
