sign of pregnancy? Implantation bleeding or ovulation?

Kasey

Me and my boyfriend have had sex a few times and always with a condom, going into my period, and then a few times after it, but not in my fertile window. All of a sudden, I’ve been bloated for a few days straight and putting on a little weight, and craving foods. I can’t tell if a change in appetite is an early sign in pregnancy. None of the condoms have torn, but I need some help. Please answer if you can. I am also getting a gooey discharge with some brown in it. I was ovulating last week, and I had sex three weeks ago. Ovulation or implantation bleeding??? Please help.
