Last month I had a normal period on time and then 19 days after I finished I started again, my period didn't come at the normal date it usually does so I've been wait and hoping that it comes 28 days after I last had it but it doesn't feel like it's coming. I feel bloated all the time, I felt sick the last few weeks and tonight was the first time I have vomited, it hurts to have sex that usually didn't hurt before, I had pains in my lower stomach after having sex as well , i also have been getting pains on the right side of my stomach
