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?

Ovarian Cyst Symptoms Check?

According to the information at WebMd, symptoms include:

* Frequent urination, if a cyst is pressing against your bladder.
* Abdominal pain.
* Menstrual period changes.
* Weight gain.

I know I’m harboring a "fugitive" on my right side ovary– (I see the doctor again tomorrow for the ultrasound) but could the 6 lbs that won’t come off be because of this dang thing? My poor abdomen has been bloated for the last 5 months since the pain came… and I work out for an hour almost every day and have a strict healthy diet, I’ve been trying to lose it but the numbers don’t change.

My question is: Have any of you cyst-sufferers gained weight b/c of your cysts? What’s been your experience?

Thank you.
