Ovarian cysts or low hcg levels?

Here’s the rundown to the point. My last period was Mar 10, 09. lasted the norm 4 to 5 days. It was due April 15, 09 and never showed. I took a pregnancy test a week after period was due, it was negative. Ive been having mild to sharp pains in my abdomen since 5 days before my expected period. It has been constant also accomodated with lower back pain, frequent urination, and pains in my breast. Ive been checked for endometriosis and ive had my thyroid checked, both test were fine. I have not gained weight nor been stressed. I usually have my cycle every 36 days. Ok I started bleeding 2 days ago which is 15 days past my expected period and it has stopped today. It was not a normal period. I only used a total of 4 pads within the two days. Im still having the abdominal pain and sharp breast pain. I also went to ER last night because of the bleeding and pain. They did a hpt and it was negative. The also did a pelvic exam which they say is normal for someone who was bleeding. Gave me some naproxin and sent me home and gave me numbers for gyno doctors. Its sat so unfortunatly there all closed. I guess its so frustrating because I have been regular for the past 2 yrs straight. Usually my bf and I use condoms or the pull out method but the one month we decide to use no form of birth control this happens. After my last period 3/10 we started having sex with him ejaculating inside me sometimes more than twice a week. And now this! Whats happening to my body?

Well 24, sexually active (pull out method), and I have been having stomach cramps. Not painful at all, it seems like Im about to start my period, or I’m hungry type of cramps. My period is every 30 days, and still need until the 23rd for my period to start so need a little bit over 10 more days ’till it starts. So I was told I have ovarian cyst by my doctor…could it be that. But that’s all I have, and it’s been going on for 3 days that I have stomach cramps and they are loud too lol but not painful…whats the deal? anyone experience this before?
