Questions!

So here’s the deal. I just came off seasonique two months ago. I have been tracking my cycle religiously, and got a super positive ovulation test last Saturday. Nine days ago. My husband and I tried three days in the five days leading up to that, and also on the night of my positive ovulation test. I had horrible diarrhea immediately following ovulation. Then starting about four days after ovulation, I starting getting continuous mild stomach aches and mild stomach cramps. Also I’ve been urinating more than normal. Yesterday I felt nauseous most of the day, but it was worse when I hadn’t eaten in awhile. Then this morning, nine DPO, I woke up with blood in my underwear. Just a couple spots. When I wipe, it’s pink. Not red. Am I pregnant?!? I took a test but it was negative. But is it just too early to tell?
