Needing advice

I'm going on almost 2 months without my period.. Up to this point I pretty much was on a steady schedule could pretty much time it down to the week.. I have tested twice but both nagitive... Been having a few symptoms of maybe pregnant.. I just don't know what to do from here? Was planning on testing again but was wondering if it would make sense to maybe do the blood test to see if I show up pregnant? Just looking for some help :)
