I have started using Ortho Evra 5 weeks ago. When I started, I was three weeks into my cycle. So, I got my period after my first patch. Then, I started a new cycle. On the patch change day of week 3, I took my old patch off, but forgot to put a new one on for 12 hours, during which I had unprotected sex and my boyfriend ejaculated inside. Now, while I'm on week 3, I have spotting, browish discharge first now it's pink. This has been going on for 3 days now, and the spotting is lessened. Since this is one week before my period and I had unprotected sex during time of ovulation, I am worried that it could be implantation bleeding... Please help!! Am I gonna get pregnant? I'm 19 year old and sometimes I have spotting before too, but this time is heavier than before!
