Pregnant or not??

Soo i need some advice!!! i was using the Mini Pill for a few months. took my last one March 6th to be precise. had some withdrawal bleed if you can call it that.. so April & May i got my period twice. And June did not get it all month. Hubby and I had unprotected sex June 16th and 30th.. was suppose to get my period on the 27th which i never did.. on July 3rd ,my period came .. but two days later idk what made me take a dollar store test . saw negative but later i saw a line, very faint. but i really think it was an evaporation line. anyway, is it possible to be pregnant and get periods? even if im not pregnant, hopefully hubby and I can be able to conceive this coming cycle :)
