Hi, I have been suffering from anaemia for a while and have only just gone to my GP about it.
Go to your GP, feeling tired all the time and having no energy is horrible, your GP will prescribe you with iron tablets after a blood test and hopefully you should start to feel the benefit.
As to your heavy periods again talk to your GP, are you using any form of contraception? The pill is meant to slow down periods but it didn't for me and my iron levels were still low. The injection and implant are better at stopping so much blood loss but can have side effects such as weight gain and brittle bones so you need to talk to your Dr, the other option is the coil but can I ask how old you are? It might not be recommended if you're young, this is the option I'm going for although it might be painful because I haven't had children, i'm going to see the Dr about it in 2 weeks.
Talk it thorough with your GP, don't let it get too bad. I missed so many Uni lectures at the beginning of the year because I was so tired and it really affected my health and wellbeing, don't let it get that far! X
