Me and my boyfriend were fooling around on the 29th. He stuck only the tip of his penis inside of me. My last normal period was on the 13th of that month & I recieved something that looked like my period just a few days ago on the 12th. The only problem is, my bleeding is lighter than it's ever been. I usually have a very heavy flow until the last day or two of my period. Now it seems the bleeding is lighter than usual. Am I pregnant? I'm also 17 if needed to know. I know what I did was foolish and irresponsible. I dont show any signs of pregnancy except for there being bumps on my areola and my period being weird this month. Please let me know if this is normal or if I possibly could be pregnant.
