My husband and I have been trying to conceive for quite sometime now each pregnancy test I've taken has come out negative, but today I noticed some light pink spotting, and I've never had that before, with my last pregnancy I didn't even know I was pregnant until I was already 8 weeks. I read online that pink spotting could be implantation bleeding. My last period was on April 11th, it was abnormally short and light. I wasn't supposed to have it until the 15th. My next ones supposed to be the7th of May.. Please help me, I think I'm pregnant but the tests say negative.
