I want to know what is going on with my body. I am 26 years old, 5'5 and 198lbs. I have four children. 6, 5, 4, and 3. As you can see they are what you call stairsteps. With my last 3 all being ten months apart. Before them I had severe cramps whenever I came on my period. After them I had none well at least when my youngest was still an infant. But recently I have been having severe cramps with my period, and sometimes twice in a month, sometimes the flow is extremely light, and sometimes ridiculously heavy. I was on the shot for about a year once my 3 year old was born. Soon after I stopped taking the shot I found out that I was pregnant and I had a medical abortion. That was sucessful although all of the doctors were amazed at the fact that I passed the embryo without any kind of pain what-so-ever. I also have taken the plan B pill two times after that. Since then I haven't been able to become pregnant and my periods are different. Im actually more concerned with not being able to get pregnant as I love being a stay at home mom, and would like one more before I turn 30, so I can have my tubes tied. Also I don't know if this has anything to do with anything but the shape of my vagina looks a little weird it looks as if the roof of the vagina fell down is this normal. Is this what is keeping my from becoming pregnant is the roof blocking an entrance to my uterus? and what is going on with my cycles?
