I've been on birth control for years, and just stopped the pill in October. I've been having unprotected sex and I'm wondering now if I may be pregnant. My last period was Nov 11-14. On Nov 27th, I've started having these weird feelings in my tummy, kind of a dull cramp, with a feeling that something is pulling on my belly button from the inside. The pain has been mostly on the left side of my tummy. I took a home pregnancy test on Nov 30th, came out negative. However, the pains still have not subsided. On Dec 1st, I started feeling bloated and on Dec 2nd, while sitting at my desk at work, I got this sharp pain in my tummy, which hurt more when I stood up. Feels like my tummy was being stretched whenever I moved. Today is Dec 5th and still the same dull cramp feeling. I also had this creamy white discharge. I don't want to take a test yet, as I am scheduled to get my period at the end of next week. Could these pains be implantation pains or am I just over-reacting to pre-menstrual pains?
