Had my IUD removed a the start of Jan because of Period problems. Started period on the 6th of Jan and my birth control Ovcon35 that day. My cycle was 4 days long. I have not been under stress or anything like that. But as of today Feb 11 nothing. I should have started the third of Feb according to my pills. What's going on?:confused:

When changing BC your cycle sometimes is not normal. This could cause your periods to become irregular. There also could be a very slim chance that you could have become pregnant. This is a very slim chance however. When I had changed BC my doc told me for the first month to use condoms or another type of BC.

You would be best to go visit your doctor and talk things over with them regards this matter... They would be the best for the advice you need.
