Hi I am a 21 yr old virgin. I started my period at the age of ten and it was regular until the age 15 when i lost it until I was 16. It has been irregular ever since then. I have had bad cramps, sore and swollen breast, tender nipples the whole nine yards. Now in the last few years i have experienced cramps without bleeding and I have been on other websites and forums and those are the syptoms of pregnant women. thats not me I am a virgin like I mentioned earlier so im not pregnant. Now I havent had my period for like 4 months now but im cramping like my period is coming and never does it show. I tried birth control to try and regulate my period but it made the cramps worse and i was moody emotional and miserable. Lately I have experienced new syptoms like a headache all day I can wake up with a headache and go to sleep with one and wake up the next day with a headache. Sometimes I have this nauseating feeling. When my period does show I have severe cramps that last the whole time which is u sually seven long miserable days.So my question is with all the information provided why do I cramp withoutbleeding?
