It is so difficult to tell

With my natural pg I had no symptoms until 8 weeks! Then with some TF I have had all the symptoms and no pg, unfortunately everyone is different and what will be a sign for me may not be for you. The only true way to tell is to wait out for your BT! When is it? You could POAS but I wouldn’t believe a - until confirmed by a BT. it’s a crewel wait.
