Spotting / Bleeding in 1st Trimester

Usually how long does spotting/bleeding last during the 1st trimester? Doctor prescribed me with dydrogesterone for 2 weeks. Its almost 6 days since I took it 3 times a day. @ times the spotting is in very light brown and @ times its dark. This only happens whenever I pee and there is no trace of any spotting / bleeding in the pad/pentyliner. Next gynaecologist appointment is on 11 Apr 2023. Any mummies out there when through the same? Feeling very anxious as back in Oct'22 I had a miscarriage. Worried that history might repeat again ? #pleasehelp #advicepls
