Could I be pregnant?

My S/O and I did it twice in October. Once with condoms, once without. I had an October period, but I missed November and I'm now late for December. I've been having very sore breasts, slight cramping, tiny bit of spotting, cravings, slight nausea, a little weight gain in my hips, and watery clear CM that only comes in small amounts. What do you think?
