Hi op, ive been in same situation really for 15 years. There is no magic way to increase your iron levels fast with supplements unless you have an iron clad stomach!!
I recommend taking the ferrous sulphate or ferrous fumarate once a day in morning. I learned last year it is best to take it on ALTERNATE days. (i was prescribed 3 tablets daily as ferritin was 7 and couldnt even tolerate taking one every day, doubled over in pain by day 5, on the loo for hours, sore bottom, stomach burning, Disastrous.
This is the evidence below for increased absorption if you take it alternate days.
Its to do with hepcidin levels rising once you take oral iron, decressing absorption. I was bloody raging when i found this out, by myself, , as have suffered so much and kept thinking i was a failure for my lack of compliance

Also google BMJ &+ sustainable prescribing of iron replacement therapy
Ferrous bisglycinate, sometimes called gentle iron is expensive (gp wont give you it on prescription) so you have to buy it yourself from boots or holland and barrett. It doesnt have the awful gadtrointestinal effects.
This is a useful reference re different iron types.

Avoid taking your ferrous sulphate or fumarate with these things
tea coffee milk yoghurt cheese, wholegrains, eg wholemeal bread or brown rice or oats, legumes. Polyphenols, phytates and calcium interfere with absorption. If you have to eat with it, apple or white bread or banana.
Spatone is fine but there is not enough by way of supplementation, unless your gp will allow you to take more. I took it when my stomach was bad.
I still force myself to eat liver.

Ive been taking the tranexamic acid TA for 10 years, probably more. I was reluctant too, thinking it wasnt natural but i would recommend reducing the blood loss by whatever means is open to you. I took it three times a day for the first two days of the period. It has a written list of scary side effects but i never had any of these. It did reduce blood flow by encouraging clotting. I never pushed to increase the number of days i took it as i always felt a little bit nauseous with it, and couldnt face another day. Also i cant take the iron pill and the tranexamic acid on the same day.
I had to be careful that my flow had really started properly before taking it, as sometimes the TA would delay my period coming out.
My heavy bleeding was due to fibroids but it took years for me to realise i even had heavy bleeding and only found the fibroids at age 48. Im 54 now, still menstruating.. They are more frequent which is why im still low iron.. Havent needed to take the tranexamic acid for the last 6 months as flow not heavy. They will stop . Ive had night insomnia and a few hot flushes......
A kind female gp told me to aim for a ferritin of 70 but i think mine is still only 24, at its worst it was 7 and i had a bald bit, and i was weeping at anything. (its the low oxygen). Optimal ferritin (iron storage) is definitely 70 upwards. Normal is not the same as optimal.
