confused

Last month I had this pelvic pain. I had a heaviness in my cervix, like it was being pulled. I had sore nipples. My husband also said I was acting off. I had ended up passing out while doing normal things like watching tv. I was very emotional. My period was late until the 29th (light) 30 (moderate) and then Halloween (light). I was sad that I had bleeding (no clotting) and checked that months off as a lost cause. Well today November 7 I was getting ready for work and got hit with nausea that was so strong I actually dry heaved. This is unlike me as if I get sick even with the flu I never throw up, I always end up with diarrhea. So this unusual action scared me. I took my temp it was 97.7 so I wasn't sick. I went to work and felt okay. However every time I smelled food the nausea spiked. I also could smell everything. I was at the front of the store and smelled the bleach they were using to clean. My mom says I can't be pregnant since I bled last month, but his is so odd for me to gag out of nowhere. Could I be pregnant ????
