advice please ladies

I came off my period around the 2nd of November, this week I have been feeling tired, as in perfect night sleep but I am ready for a nana nap by 12. Yesterday I had bad leg ache which I get when I am tired but again had a perfect night sleep. Today I have had sensitive breast not painful but sensitive  and just recently when for a wee and had light bleeding. Is this early signs of pregnancy ( really early ) or is it me coming on early. Of course ttc but don't want to get  think I need to buy a test for no reason. Thank you 😘
