Any ideas what should do?

My last period was 27th December till 31st december, between 13th and 17th of January I had really bad headaches then 18th and 19th I had light cramps on 20th January I had one lot of brown sticky cm and then one lot of pink sticky cm and then on the 23rd January I had sticky white cm and since then I've been having a lot of clear white watery cm! Any ideas? On what's going on? Thank you!! Xx
