Okay so I am 19 almost 20 and my boy friend and I have been trying for a baby. Anyways, I was susposed to start my peroid Jan 17th and its now Jan 22. Yesterday morning i had a little blood, i thought my peroid was starting, but it stopped after an hour or so. ANd it still hasnt started again. 2 days ago I bought several pregnancy tests and the first and second ones there was a light line the size of a pen mark, does that mean pregnant? But I took 2 more and they were negitive. What do I do and who thinks they know what is going on? I have been feeling sick but havent vomited yet. Please write back soon. Thank You
