Womens Conditions Forum - Bleeding During Intercourse

Hi
I have a problem and unfortunately my gyno cant get me in until october 3rd. So at this point I just really want someone to talk to. But I dont want to worry any of my friends and family. My fiance is pretty much the only person who knows about all of these things. If you have any idea what this could be, or any suggestions please write me!
A little over a year ago I had a miscarriage, at 12 weeks pregnant. Then about 6 months ago I started having some problems. I started bleeding whenever I have sex, its not heavy, its actually little and brownish. But its not just when I have sex, I spot throught the course of every month. Having sex is the only time I know it will always happen though. Other times I cant predict when I will start to bleed, there are no signs. Its gotten so bad that I refuse to have sex and have only done it maybe 5 times in the past 6 months.
Also my periods have been very irregular. The past 2-3 months my periods have also been painful. Bad cramps and such. This month though it was so painful, I had to lay down on the floor with a heating pad and take midol for a couple of hours. I couldnt stand moving and it hurt so bad at times that I felt like I was going to cry. My fiance and the girl that I nanny for were very worried.
This past month around my period I started getting brownish spotting, this went on for approx 10 days, then I got the heavier bleeding like I usually do at my period, this lasted for 3-4 days. Now since the heavier bleeding stopped it got very light and brownish again.
Also, my abdomen has been bloated alot, its not constant though, but most of the time its bloated. Im a very tiny girl, I have never been able to gain weight regardless of the fact that I eat like a pig. But now my pant's are too tight. I have also been hungry alot. In fact almost every morning I have woken up early just because im hungry.
The past few weeks I have also been very fatigued. It's not that im tired, but I always feel this tiredness in the back of my mind. Like I cant concentrate. My fiance has also complained lately that I keep zoning out.
Occasionally I have also been getting slight pains in my side, but very slight and hardly ever. But this has been going on for about 4 months.
The only other thing that has happened is that I have to pee alot. I mean I wake up alot during the night to pee. And if I dont pee just about every hour, my stomach gets so bloated. Honestly it ends up looking like im pregnant. But I cant be because I had my period so I dont have any idea whats going on. Please write me and tell me what you think.
