Why Am I Experiencing Burning Pee and Nonstop Bleeding?

When sexual activity occurs during menstruation, it can potentially disrupt the normal flow andcause the bleeding to taper off earlier than usual. This is generally considered normal and should not be a cause for significant concern. If you're concerned then please do a test to confirm.

I advise you to go to a gynecologist immediately. Rashes in vaginal area can be a sign of a vaginal infection or a sexually transmitted infection.
 

If you’re worried about a possible pregnancy, don’t be. The chances of it happening from what you’ve said are very slim. If there was no ejaculation or confirmed pre-cum inside her, then there is almost no risk at all. Stress can also delay periods. Tell her to relax as much as possible. If her period still doesn’t come, take a home pregnancy test to be sure. 

Pregnancy is unlikely. Your period on the 29th would have been too early for implantation bleeding . Bleeding on the 2nd of this month could be hormone related, due to stress, or a vaginal infection. See your gynecologist for an evaluation and some blood and urine testing.

Experiencing irregular periods and changes in menstrual bleeding can be due to causes. It's common for periods to vary in terms of flow, color, and duration from time to time. Dark blood at the beginning of your period can be normal as well.

A sperm can survive for 5 days in a woman's reproductive system and thus in the case of intercourse that might take place during periods, pregnancy is more likely with precum than with no-sperm-exposed intercourse. Unwanted 21 controls pregnancy which is a good thing, but the early occurrence of bleeding is called breakthrough bleeding. It is your body that is adapting to the pill. Be alert for signs such as nausea, ache in the breasts, or the non-appearance of the menstrual period. Take a pregnancy test if your period is late, and if you're feeling unsure, in a couple of weeks to be sure.
