I don't get it!!

Tomorrow makes 10 days late, I only get BFN, husband and I have been trying for a baby since last mothers day. Last July he and I had a chemical pregnancy, so I have no idea when I ovulated, Hubby and I had sex about every other day if not every day up until I was supposed to get my period. BUT no period and its been nine days. I have a couple symptoms such as lower back aches, VERY sore nipples and boobs, twinge feelings in my abdomen and boobs and A LOT of CM. It's a yellowish/brown color and I've read that is normal for early pregnancy, however, again only bfn's. When we have sex it feels funny being on top, it doesn't hurt like when I am close or on my period, the feeling is just funny. I dont know what to think! Should I just wait and wait to see if I get my period or when do you think I should set up an appt with my doctor?
