For the last few days I have felt like I was going to start my period. Two days ago I had some spotting and bad cramping. I still have the cramping, and the bloating but the bleeding just stopped. I am on the hcg diet. I take the sublingual hcg. I stopped taking the drops as directed when starting menstruation. I did also do a home pregnancy test which came out negative. Do you think this may have something to do with hcg, although I haven't been taking it?
