On Saturday I woke up awful, super dizzy and tired as well feeling like I needed to be sick. I couldn’t even eat, I just feel awful. I was fine yesterday, ate a bit and was able to walk about but stomach was really sore. Now today, I had to take the day off work because I constantly felt like I was going to be sick. My stomach literally feels like someone has punched me, just where my ribs are. Can anyone think of what it is? My period finished last Saturday, I had sex Sunday morning and took my pill on Monday.
