Yes, that can be normal. I get back pain, stomach and uterus pain and a little pain down my legs. Ibuprofen and paracetamol can work well. Normally you will need take it for the first 2 days, but everyone experiences different heaviness and pain. Some people have bad pain the whole time.
Just as a PSA to anyone.
It is not normal to have very painful periods or very heavy periods. You shouldn’t have to force yourself through the day and then feel horrible at home. You can go to the doctor and get specific medication for the pain during a period or if that doesn’t work then, if you want to, you can take the contraceptive pill to either reduce the pain or stop it altogether if you want to. That is the route I went down.
Had to take days off school for pain, felt horrible for the first two days and was forcing myself through the day with a smile on my face. I went to the doctors and got mefenamic acid (spelt it wrong) (also, if taking, it may be helpful to take some the day before your period starts as well to prepare). That worked for 2 to 3 years and then the effect of it started to wear off, so I have started on the contraceptive pill. I know that some people do not want to take it either because of health worries, religion or other, but for me realistically there was no other option. There should always be options other than forcing yourself through.
Hope this helps anyone (and not to scare the original poster)
