Most women will probably agree - periods are really annoying.
As well as the stomach cramps and all those extra emotions flying around, they actually cost you money thanks to pricey tampons and sanitary towels.
But one woman might have just come up with a brilliant solution - period pants.
Ruby Raut's St Albans based company WUKA has just released the new underwear, and it can be worn without any other sanitary products.
The reusable pants cost £30 but Ruby claims they will save women hundreds of pounds in the long run.
The 28-year-old said: "Females need this product. This will solve the problems of anything and it is ideal for anybody, of any age.
"I wear them myself, I have got three pairs.
"The knickers are very absorbent and dry instantly with no liquid sensation happening in your knickers.
"The menstrual liquid passes through the wicking material, which is used as suction, it holds the liquid and interlocks so nothing comes up.
"It is only when you are washing them in a lot of water then the blood comes up."
Women can wear the pants for up to 11 hours, and they have three layers of protection including "super comfortable" hi-tech fabrics.
They contain a built-in Polyutherine laminate fabric leak-proof pad which is reusable and has re-washable anti bacterial properties.
The absorbent layer can hold up to two hundred times its own weight in water and at least four tampons worth of menstrual blood.
Ruby said: "It is basically three in one underwear and is 100 per cent better than towels because there is no shifting or wedging of the pad.
"Plus after you wear it for a few hours you won't get the irritation that the many women usually get from pads."
WUKA claims a pack of five will save women about £500 if they use them for two years.
And the clever pants can also be used for postpartum bleeding or a leaking bladder.
Ruby said: "Women spend thousands of pounds just on their periods. Not to mention the bed sheets and knickers we have ruined.
"We have created one comfortable design and style and overtime we will reiterate it to make it the most comfortable and ideal underwear for your period.
"The underwear does the magic and holds in all the liquid."
Mum Susan Kiely, invested in a pair of WUKA knickers for her 17-year-old daughter who has Down's Syndrome.
She says they are especially great for people with disabilities as it gives them privacy and is easy for them to change.
Susan, 50, said: "Can't believe this idea hasn't been done before.
"My daughter has worn them for almost 11 hours in the heaviest days of her period and there is no leaking whatsoever.
"They are comfortable and so easy for her and she needs no prompting to change pads like she did before.
"They are perfect for special needs kids or for girls who do a lot of sport and for just any girl really.
"I must say I would highly recommend this product."
The pants go on sale this month and are available in sizes 6-20.
