I've been ttc for 18 months. I got what I thought was my period on Wednesday, but it only lasted one day. It was a heavy flow for a few hours, and then it ended. my periods usually last 3 days and are very heavy.

I threw up on Friday night and have been nauseous, have had headaches, and have been so irritable and sad the last few days. is there a possibility that the bleeding I had wasn't my period and that I'm pregnant? has anyone else experienced something like this?

would really appreciate any and all help.
