Early signs of pregnancy?

Hi ladies,

Im ttc my 1dt baby. The past 10 days iv had a headache and lower back ache, Friday and today iv have mild nausea. My nipples are really sensitive. Thursday night I had awful sharp pains in my left Ovary lasting a few hours and I feel extremely bloated.

My period isn't due for 7 more days. Are these signs of early pregnancy. Baby dust to you all 💜
