testing too early or false alarm?

I took two tests both came back negative. my partner and I had unprotected sex during my fertility window mutliple times around the 7th& 8th of Jan - 14days later i had light bleeding and pink spotting for a day and a half, 4 days before my period was due & since then I've had sore breasts, backache, fatigue and increased hunger - probably reading too much into this, maybe the spotting was my period (but that never happens to cycle). Its almost 14 days since the spotting thats why i tested - but they were both negative. Could i be testing too early? or just a cycle with a weird period?
