Menstrual or period blood should be very dark red to brown. The uterine wall is also shed along with the unused egg during this time so there should be thick "goopy" aspects to the blood as well. Blood that is full of oxygen is bright red (like when you cut your finger on something). Menstrual blood is mostly used blood which is dark red/brown. Most women will have times where the blood will change in color and texture throughout the days of their period. It may come on as a lighter color, or it may be the other way around. Any changes to what would be considered regular for your system should be investigated with your doctor. If you are having heavy cramping, pain and heavier than what is normal for you blood loss, then it really is important to see a doctor. I'm not saying this to scare you, because usually period problems are not serious and easily fixed.
It's not a good idea to put anything in the vaginal canal with the exception of things destined for that area (obviously sex organs, tampons, and etc.). The compound in garlic that kills yeast, as well as many viruses and bacteria is called allicin. The only way this compound will get to your vaginal canal is through your stomach. The vagina is not able to "break down" garlic to release the allicin. Whereas your stomach does exactly that and allicin is released directly through the stomach lining to your bloodstream and travels throughout your entire body.
The burning you are experiencing during sex could possibly be due to a vaginal yeast infection. As I'm not really sure what you are doing to "cleanse candida" I can't really say.
The burning sensation when you urinate is not likely linked to candida. If you also have a need to pee a lot during the day but only have a little bit of urine and it burns and hurts when you pee, then that is most likely a urinary tract infection (UTI) or cystitis. This too will be easily sorted out by visiting a health care provider. Some women are very prone to cystitis. One way you may find you can avoid these types of infections is to carefully clean the entire groin area (front and back) (soap and warm water wash cloth are great) immediately after sex. The bacteria that are supposed to be in the vagina find their way into the urinary tract often as a result of sex. Also, if you feel an infection coming on in future, drinking cranberry juice will help you avoid a full blown infection (there's enough clinical data that this is worth doing).
There is one more thing you may want to consider. Your gut symptoms are not completely gone by the sounds of it. And it is possible that a vaginal yeast infection, a urinary tract infection and continuing gut symptoms all indicate an as yet unidentified underlying infection. Yeast is an opportunistic organism and it is supposed to exist in our gut. If it didn't we couldn't metabolize a whole bunch of vitamins. You only get yeast blooms when the balance is upset. And that often means an outside invader.
I would suggest you ask your health care provider if you could have stool sample tests taken. It's not hard to do (no needles at all). You would want a CS and O&P stool sample test done. This will check for intestinal worms and parasites. They are often the reason for intestinal yeast blooms. Furthermore, there is a strong link between
parasites and repeated vaginal yeast infections, urinary tract infections and eye infections as well as something called reactive
Arthritis (inflammation in joints and muscles (fibromyalgia) and occasionally the heart muscle).
And finally, if you have any
Amalgam fillings (silver-colored dental fillings) in your mouth -- especially if there are more than three, then you may have to deal with the replacement of those before your intestinal, vaginal and urinary infections can be successfully treated. The clinical data indicate that people with mercury
Amalgam fillings (the silver colored fillings) are far more likely to experience gut problems (infections) than those who have no such fillings. The data also suggests that while you do have these kinds of fillings the bacteria, yeast and
parasites are more resistant to
Antibiotic and antifungal treatment than after the
Amalgams are replaced. What this means is that you can treat all the infections and they just keep coming back until you get the fillings replaced in your mouth.
I am sorry mine is such a long post. I hope some of this is helpful.
