My husband and I had sex with a condom but it slipped off as he finished. It was on a Friday and I was ovulating a few days later. The Tuesday after I had cramps all day long and the next day a little spotting. That was last week. No new symptoms that I've noticed. Im wondering if i could be pregnant? Was tha cramping and spotting from implantation? I have a 21 mo that still nurses so not sure if that would hide/cause symptoms. TIA
