For about 2 or 3 weeks I have been having symptoms of pregnancy like mood swings, increased appetite, sore breasts, nausea. For the last couple of days I've had mild cramping in my lower stomach and my lower back.

I've been seeing those little bumps on my areaolas lately that I have never noticed before. My period last month was weird. It went the usual 4 days and then it stopped. The following day, the 5th (which I never go more than 4) was very light, pink when I wiped and then it stopped. December 11-15th. I had unprotected sex the day after, on the 16th. Shortly after was when those symptoms started, especially the mood swings, the nausea and hunger. Two days ago I started feeling cramps but there was no bleeding. That doesn't usually happen until the day I start my period. I did take two pregnancy tests. The first test showed negative at first. When I looked a little later there was a faint sign making the + sign so I got a digital one that said Not Pregnant. I started bleeding last night. It was light pink all night and still light this morning. Now it's just red, barely showing up until I wipe. Normally, it would be dark, dark red/brownish. Could I still be pregnant?
