Pregnant?

So I missed two of my birth control pills on the 6th and 7th of September, I did not double up or anything bc it gives me serious side effects. He did not pull out on the 4th and the 15th. So I was supposed to Originally start on the 13-14th according to my birth control pack and I didn’t and still haven’t. I took a test this morning and it was negative. Any suggestions? I’ve only had a tiny bit of cramping and some increased cm. But that’s it.
