I am on birth control pills so I think this is why I am really confused. Last month I messed my pills up because I dropped one down the drain oops and then I missed another... so I ended up missing 2 pills last month. Well I started my period when I should have started which was on July 18. It was pretty normal I guess and it lasted until July 22. Now its July 30 and my breasts are very sore and feel VERY full. The only time they have ever felt like this was when I was pregnant with my son. Last month I was obviously pretty worried about getting pregnant from missing 2 pills considering my husband and I never use protection other than the pills. But I had my period so I assumed everything was all right... I even took a HPT the morning that I started my period and it was negative. Is there anyway that I could be pregnant?
