Irregular periods- what will the doctors say? Advice please.

so we are in May this year already and I've had a total of: 2 periods. My cycle lasted 45 days last time, and my current cycle right now- I'm on day 47. Still no period. Negative test.
I know some doctors would advise the pill to kick start my body and make be regular but I can't take that as I'm diagnosed with migraines and I'm high risk of a stroke. 
I'm going to to doctors next week to have a talk about this as I'm concerned something is really wrong. This is so out of tune for my body. Has anyone else experienced this? What did the doctors say to you? Really frustrating as we really want a baby!
