Confused looking for help.

Nicole

Saturday I got my first positive pregnancy test we where very happy! i took clear blue and my period was two weeks late I started getting really bad headaches witch is something that doesn't normally happen, I got pimples and I just am very sleepy and hungry. then Tuesday I retook and it came back not pregnant. I was very upset And didn't understand and I'm unable to get into the doctor till tomorrow. now today Wednesday I woke up and I was bleeding abit I'm going to be tracking it thought the day but I'm very worried and very confused this is the first time I've ever got a positive test and my husband and me where so happy.
