skipping two in a row?

em
Hey everyone, so my next two periods are due on my birthday and for my 3 year anniversary with my partner.
I've been on the pill since May 2015 (21 days active, 7 inactive), and have only attempted to skip it once, (July 2016), but it didn't work out, and I ended up spotting all the way until I took inactive pills again.
I'd rather not have it for my birthday and anniversary, but am worried about skipping two periods and spotting again. Any advice? Xx
