Help!

Hi all. My husband and I are currently Ttc. I have been on the pill consistently for atleast 5 years. I went off bc April 18 and had my period right away on April 21. I had my next period June 2. For the past week+ I have been having period like cramps and bloating. I took a test on Sunday and it was a bfn. I haven't had any of the other common symptoms like nausea or tender breasts but today I am feeling slightly lightheaded. I don't know what to do since I don't know my regular cycle yet and I don't know exactly when af will come. Has anyone had similar experiences?
