I gave birth last nov 4, 2011 via c-section... after 3mos, I had my 1st mentruation... I bled for 3 weeks... its not like my usual mens, its only light, I only used 1 pad per day... after that, no menstruation again for march and April... I have something in my stomach... its like a mass or a lump... it doesn't hurt... but I'm not comfortable with it, bcoz its getting bigger I think... what could it be? I hope anyone can relate to me... and can answer or share with me some some answers... thank you...

What are the chances you are pregnant again?
You should go see a doctor about this, there is not much any one can tell you on line.

I test for a few times.. and its negative... so I'm not pregnant... :(

I think you should have it checked it out by your doctor, though not painful, being uncomfortable about the fact that is there is going to stress you until you get an answer.
With a six month old added stress is not something that you need.

I second Lady Sam's recommendation. I'm really sorry, but no one can give you an accurate diagnosis online. It would be really nice if we could, but anything we tell you would be a guess. Guesses won't help you.

You need a doctor, and I'm shocked that you haven't already gone to one for a follow-up after your c-section.

Please, see a doctor, that's really the only way you're going to find out what's going on. Relying on info from the internet is putting your life at risk. You need an actual diagnosis, not guesses.

Please let us know how it goes, but really, there's nothing anyone online can tell you that will help. Not even a doctor can diagnose online. Anyone that says they can, is a scam artist. Here, on this site, we actually care about your health, that's why we won't even guess. Doctor, right away. Okay?

Are you breast feeding your infant? Some women who breast feed don't get periods or very light ones. The lump or mass could be any number of things so your best bet is to see a doctor about this...
