Why are my period so clumpy?

It is probably thick due to the fact your period was so light last time: it can happen like that, as there is just more to come out. I would say, if you are having to change your pad or tampon more than once an hour because of it, then go to see a doctor. The same if it is this heavy for longer than 2 days. Try and take iron tablets in the meantime too, as you will be losing a lot due to bleeding.

I do get this though, as do other women I know, so I would not worry too much. Just keep an eye on it :)

It is normal, it is just that the lining of your uterus has not broken down as much. I get the same thing, but if you are bleeding extremely heavy then I would talk to a nurse. It may be that she could put you on birth control, such as the pill, in order to help lighten your periods and cause you less pain. It can be really effective in this way, not just as a contraceptive.

The pains you were getting just sound like regular period pains. Try heat pads (available from all drugstores) or painkillers such as ibuprofen to help with the pain.

Don’t worry though, you sound normal and many women get clumping like this too.
