Okay so aunt flow is suppose to start tomorrow (hopfully not) but yesterday after I peed and I

wiped and noticed light pink so I assumed begginging of my period. I put a tampon in and went on my way. A couple hours later I went to change it and there was a very tiny amount of brown blood. No cramps or anything so I put a small liner on to see if I had any more leakage. Nothing for the rest of the night. This morning I woke up and wiped this... the pictue. So still no cramping which is VERY unusual if it is my period. I ALWAYS cramp bad in the beggining. Could this be implantarion bleeding?! We had intercourse about 10-14 days ago which would make since if it is. Opinions please?
