How long Mild cramps last?

P🌈 mom

Hi ladies, i am 3 weeks 6 days based on my last period. I tested positive at 9 dpo and have very sore breasts and nausea continuing since 8dpo. Tests are coming out positive since 9dpo. Today i am having mild cramps on just my right side pelvic area. I wanted to ask if its normal or should i be worried? Its a rainblw baby so i am being very careful
