I could use some advice

Shelby
I'm not 100% sure I'm pregnant but I noticed my lower abdomen had been hard for a little while but I though it was just because of my condition, I have PCOS. More things have started to happen though. It feels like a heavy weight in my pelvic area. I'm using the bathroom more but I'm constipated. I am very moody, just last night my bf made me mad and a couple minutes later I was crying for no reason. Yesterday I drank a shake and thought I was going to vomit and the same thing happened when I took a drink when I woke up this morning. I thought I just ended my period a few days ago but it was light and not every day so it could have been spotting but last night after sex I was bleeding. I just need some advice and I'd like to get some opinions if you think it sounds like I'm pregnant or not.
