6 day Late period.

Hi. I have a healthy 4 year old and have been trying for the past 3 year to have another baby. I was due on the 23rd August, but still nothing. I have done 3 pregnancy tests on different days and different times of the day but all been negative. I'm hoping it means I am pregnant but until I get a positive I am not sure. Been late before but not this late. I have Dr appointment soon and if nothing before then, will see if can get a blood test to tell me. 🤞🤞🤞🤞🤞🍀🍀🍀🍀

Also, I have been nauseated, tender breast, moody (more then usual 😂), constantly eating. I know these could mean I could still come on or be pregnant.

Thanks 👍👍
