I hate doing this....

I never get a true answer when I do this but I'm going to write this anyway and see what I get. I've never been aware of when I ovulated, I've never kept track. This time I did, I ovulated the 11th oh this month and did the baby dance that night. Every since I've felt a little off. Not a huggeee difference but enough that got my attention. For the life of me I can't understand any of what's going on, and I don't wanna get my hopes up again because I've had a false alarm in December... Anyway after the 11th around the 12th that night I started to spot. I had just gotten off my period the week before and I wasn't expecting anymore blood to come out of my body. After the spotting I was like eh guess I'm not done and brushed it off, I did it again last night and I woke up hot, sweaty and in the need to pee but after I went it went away. Well between the 11th and now I've felt.. strange. I can't only eat a few things simply because it won't turn my stomach, I can't sleep on my right side because it kinda hurts, i sleep longer than normal and even when I sleep long I wake up tired. My boobs at one point were tender to the touch but now it's fine and I feel bloated. Does anyway know what this could be? Please comment and ease my mind, I'm thinking every possibility under the sun..

--P.S my friend thinks I'm pregnant, but like I said I don't want my hopes up.

--Forgot to say this be I've been feeling faintly nauseous as well like all the time, nothing ever comes up tho
