Hello I am new to all of this and trying to get some advise. I finished my pack of bc in December of 2017 after being on it for probably 4 years and  went till July 3rd with no bleeding..on July 3rd I started bleeding and just stopped yesterday July 14th. Does anyone have any ideas of what that is? I'm also trying to get pregnant I'm starting to get frustrated because I don't know if this was withdrawal bleeding or a period. I took an ovulation test and it came up negative.

Any advice would be great

Thank you
