Hello. I had protected sex 20 days ago on the first day of my period. I'm worried, because today I had some spotting. It's 5 days after I was expected to ovulate. I've been having on and off cramping for the past week. My cervix is low, hard, and open and I'm experiencing some vaginal dryness. My period isn't do for another 8-9 days. I took a pregnancy test and it came up negative, but it may be too early to tell. Is there anyway I can be pregnant?
