Pregnancy Info HOME

I have VWD which is a blood disorder and causes my periods to be unpredictable. Sometimes they are heavy, sometimes extremely light but they only last on average 2-3 days. My last period was on July 29th and was extremely heavy for one day. To the point I thought I was hemmoraging (sp?). I had unprotected s_x on Aug 14th and haven't gotten a period since. I have no pregnancy symptoms, but from what I've read that doesn't mean I'm not pregnant, as it's only been almost a month since conception could have occured. Yesterday, September 10th, I was planning on going to the store to get a preg test but when I went to the bathroom I noticed there was blood (bright red) in my underwear. I was pretty happy, as I'm not trying to get pregnant. I put a tampon in and when I changed it there wasn't that much blood. I put a pad on so I could monitor how much I was bleeding better, and I really only bleed while I'm going to the bathroom. I've been under so much stress financial, and about being pregnant so maybe that's why my period's light. I was just wondering if there was a chance I was pregnant still with this bleeding. I've read everywhere that "implantation bleeding" happens much sooner than I am experiencing. Could this be a period that's extremely light due to stress? Or could this still possibly be spotting due to pregnancy?
