I'm currently on the pill but there was a problem with insurance and I stopped taking it for a few months and when I started again I took about half of the pack and kept forgetting to take my pill. So I thought it would be a smart idea to jump in right where I left off. :| which then made me have a 3 day, very light period starting March 3rd. Fiancé and I had unprotected sex around Easter because  he came down for the weekend. I am 3-4 weeks late and for the past week I have been nauseous, tender nipples/breasts, dizzy, I feel like I'm not getting enough sleep, loss of appetite, constipation and mood swings/emotional easy. I've been having cramps like I'm going to start my period (but I haven't) for about 2-3 days and this morning I noticed that when I wipe it is a very faint pink color and it looks kind of like mucus. I've taken 3 negative hpt, is it still possible that I could be pregnant?
