Is it possible

I've been trying to conceive for 2 months. My minstrel cycle ended the 27th last month and we immediately started trying again. The 29th I started spotting and since then I've been cramping and felt sick iff and on. Is it possible that I'm pregnant? My first two pregnancies I just knew I was as soon ss I had sex. I feel the same way now but I don't want to convince myself I am when I'm not.
