No, what you are experiencing is not normal. If you have been to a OB/GYN and had any pathologies ruled out, (such as uterine fibroids)then I would suspect that you are progesterone deficient. I would suggest for the cramping a product called Cramplex tablets. This product is made by a company called MediHerb out of Austrailia. Unfortunately it is only available through a doctor. I would recommend something more available, but I have found nothing to work like this.
This combination of herbs works well for spasmodic dysmenorrhoea (painful menstrual cramps). It combines the antispasmodic effect of Cramp Bark and Wild Yam with the analgesic activity of Corydalis. Ginger improves circulation, is warming and anti-inflammatory as well as inhibiting the synthesis of less favorable prostaglandins. Raspberry Leaf is astringent, therefore may help to reduce excessive bleeding. It is also an excellent female reproductive tonic.
The dosage is 3 to 4 tablets twice daily For best results begin taking Cramplex tablets 1 to 2 days before menstruation is due to begin. Caution is advised in Gallstones and those taking antacids. If very high doses (more than 10 tablets/day) is prescribed caution is advised in those taking blood-thinning drugs and those who have risk of hemorrhage.
I would suggest that perhaps you try some OTC sublingual Progesterone tablets. Ideally would be to do a saliva test and check your hormone levels, but low dose progesterone is relatively safe and should help. I would advise against progesterone in a cream form as we find on testing that too many women end up getting extreamly high levels of progesterone in their bodies.
Hope this helps. Let me know if you have further questions.
