Help please x

Cerys
I'm 3dpo (if i ovulated when i thought i did however this month i didn't use opk) and today ive had extremely heavy cm and clear, near enough water like, and i think i may have a uti (waiting on doctors appointment) i have tablets to take for my skin and iron levels that i CAN NOT take whilst pregnant and i know implantation dosnt normally occur until 6-8dpo however theres a possibility i ovulated earlier than though or theres always early implantation, so the question im asking is should i stop taking my tablets as a precaution?
