Serious inquiries only. Menstrual period abnormalities.?

On December 24th I had sexual intercourse a # of times (the day of the accident)as well as the following day. The thing is....the 24th was the day after my period ended so I should have been safe. It is not unusual for me to have long cycles usually about 30 days. My last period started on the 17th of December. Therefore, I shouldn't have ovulated until about the 31st. Approximately the 25th day of my cycle I took my first pregnancy test. I also did an additional test around the 30th day. On the 41st day of my cycle I started spotting (4 days ago). It was light enough that I would only notice it when I wiped. Tonight I finally got a little bit of a flow but it is very thin and has an orange tint to it. It's also not very heavy at all. I did a 3rd test (-) and plan a 4th nxt week prior to Dr. appointment. I have been taking Adipex for weight loss and have lost 20lbs in in past 2 mo(reason for mult. tests). My current symptoms-nausea,tender breast (bf .), dizzines

Maybe you are PG

when you take birth control or weght loss stuff it messes with your period and makes it kinda go out of sync. like for some it is the beginningof the month or themiddle or the end. mine is messed up to and no drugs taken. if you stop taking drugs for weight loss your period will be normal again. abnormal flow or cycle doesn't mean pregnant. sounds almost like you have a yeast infexction if it is orange . if it has a smell id suggest getting some monistate one dose ovial stuff it will help alot..
