Hey ladies I need some help

So my husband and I are trying to Conceive for baby #2. my cycles were regular before I went of BC. now they are all over the place with coming off of it. and not sure how to track. I try tracking my CM but sometimes it's hard to keep up. I'm not sure when to test now. I had a normal 28 day cycle in April and I had a period April 1-5. then my period came a week early and was the 23rd-28th then I spotted from the 9th to the 16th. never got a heavy flow. I Have been taking tests and they are negative so that was not implantation bleeding. I'm not sure when to test now. When to expect a period. I'm so confused. lol maybe it's better this way so I don't track every second of a tww. any opinions??
