I know that waiting time can make you feel so anxious and you keep checking every little symptom. It's very common to feel light cramping or bloating even a week before. Sending you lots of love!
For me, my breasts felt extremely sore and heavy about 5 days before my missed period. It was very different from my usual PMS, and that's how I guessed!
My nurse at the clinic told me that hormone levels are too low to cause major symptoms so early. It's best not to stress and just wait for the missed period to do a proper test.
Implantation happens around 6-12 days after ovulation, so you might start feeling mild fatigue or breast tenderness around then. But biologically, symptoms are very similar to PMS, so don't stress too much before your missed period.
Honestly, before my missed period, I was just super cranky and blamed it on PMS, but it was actually my baby starting to keep me awake already! Some women feel it in a week, some feel nothing.
