Waiting on af but weird symptoms

Jess • girl mom + boy mom x2🖤
My number just hit negative last Tuesday from an ectopic that was treated with methotrexate. I bled for 29 days & it stopped May 10th. I have yet to start af. I've been feeling crazy nausea the past few days, very emotional and moody, no appetite....same exact symptoms I experienced before my bfp with ectopic...we have not be too careful with things since the bleeding stopped. Anyone know what's going on? I heard af can take awhile to restart
