What's going on? :(

[nerdygf92]

So, my last period was on 10/03 and I'm almost a month late now...I've had two tests, one at the local health dept. and one at home. Both were negative (health dept. one week late, home two weeks late). I've had light cramps on and off since late October, headaches that come and go, nausea that comes and goes all day, I've vomited several times in the past two weeks (for no reason at all), and many other symptoms.

I went off of my birth control for a few months (I lost my health insurance and had to wait for an appointment to get the birth control from the health dept.) and now I'm on a very low dosage of orthotricylene (sp?). The nurse said to come back at the end of this pack if I haven't started and I'm just really nervous. I had unprotected sex a few times in the time I wasn't on birth control. Advice please?
