Pregnancy Question regarding Positive Test

Patient: I took a pregnancy test a couple months ago and it came back positive, I then started bleeding a couple days later, which would have been the date to start my period. My doctor said it was my period and a cyst on my ovary casued the positive test.I am 2 weeks 3 days late on my period and I have had numerous positive pregnancy tests. I have never been late on a period before, my breasts are sore, nipples are sensitive but not much, and I feel queazy and sometimes find myself gagging. Also I have has some episodes of dizzy spells. I also have noticed very mild and achy cramping but its not unbearable, just more anoying than anything else.Could I be pregnant and this cyst is not throwing me off again?
