Pregnancy Info HOME

Okay so I'm on a pill that allows me to be on my period every three months. It always comes around the same day each time. The only reason I got on the pill was because I wanted a little extra help to try to avoid getting pregnant. Before the pill my period was normal. I have never spotted in my life and it always lasted about 3-5 days and is fairly light the whole time. And now that I'm on the pill it's pretty much the same way. My period now always comes at the end of the month or the beginning depending on which day my pills make it fall on. I've also, NEVER missed a period. With that being said, on the fourth of February I had unprotected sex but the guy pulled out. A week later I started spotting brownish blood. With a little research I thought it might have been implantation bleeding. This lasted for almost 2 and a half weeks. And I only needed a liner to last all day with it. It stopped 2 days ago for a day and then yesterday I thought I started my period because it was redder and more of it. But only a little came out after a few hours and then stopped. I took a test Saturday and it was negative but it was an older test so I believe it was expired. At the moment there is dry blood on my pad that I had put on at 2 o'clock this morning. I have been sorta cramping randomly but really only in my sides and not like a normal cramp. And I also don't really feel like i usually do when I'm on my period. I've also been moody and constantly hungry. Is there something wrong with me or am i possibly pregnant??
