I had protected sex a week ago and was spotting for two days after, then stopped. Today I noticed a light pink spotting, going to the bathroom a little more often than usual, and a slight tugging feeling similar to a very mild cramp. Also I m starting to take into account of a peculiar smell down there, and a bubbly sensation coming from my uterus area. Multiple condoms were used, neither one broke, and he never ejaculated. Could I still be pregnant?
