Off BC and now TTC

Hello Ladies,
I've been on BC for 10 years and I finally decided that I would like to get off and whatever happens happens from there. I went off BC in feb. I had a cycle in February and March. In April i spotted for 4 days and I'm may I didn't see anything. We have been having unprotected sex a little often. Now for the last two days I have been bleeding. Do you think it's my cycle trying to regulate or possible pregnancy I've take three test and all were negative
