After a year with marina coil my periods are only ever 2 days and very light. They were never like this b4.Ive been trying for 3 years now to get preg?

Need evaluation. I don't know how old you are, but if you've been having unprotected sex for 3 years now and haven't gotten pregnant, this is, by definition, infertility. This could be your issue, his issue or a combination of the two. It can take a while to get a routine appointment in the NHS, so call your doctor's office today. Best wishes. Dr. Anne.
