I was wondering if anyone else has had the same problems as me!

I was on bc after my daughter who is 2 now. in July we decided it was time for one more.. BUT I haven't had a period in close to a year. Went to the doctor took test and nothing seems to be wrong, the doctor wants to put me back on bc to help regulate a Period. I told him I really don't want to be on it again. Anyone else have this problem? Will it be hard to conceive? My doctor doesn't seem to care I want another baby.
