Pregnant Or not is the question?

I have been off my birth contol for about two months. However, I have been having pregnancy symptoms towards the end of May. I have been increasingly tired, enhanced sense of smell, increased appetite, nauseau and vomitting, bloated, headaches, sore breast, I have also had cravings for citirus foods like oranges, and grapefruit. I also had eaten pizza and ice cream, and marshmallows and green beans? I started the vomiting since last weekend. I’ve also taken frequent trips to the bathroom. The catch is that I now I’m on my period; regular not light since Monday (6-7-05). Is it just me or am I some how confusing pregnancy symptoms with pms? Can someone help me on my confusion? Thank you for your time 🙂
