After I have sexual intercourse for the next couple of days my vaginal secretions have color in them?

After i have sex, my vaginal secretions are clear like noraml but theres like parts of them that are dark brown or really dark, or sometimes its like a spot of blood in them, is that normal if it was to rough or hitting against my cervix? the sex wasn't painful just afterwards later on when i use the bathroom theres a clear secretion with dark brown or blood in it, has anyone ever had this? my periods arent regular at all and i haven't gone to the gyno, but i read that black secretions are a sign of cancer or hpv. I am really scared and worried. Also in my arm pit theres a like a lump thats hard and inside and i know its been there for a long time and when i press on it, it kind of hurts what is that? please someone help me.

First problem, the post-sex spotting. That's what you're getting. If you are having this after non-rough sex, it might be a sign that your cervix is friable (meaning that it is inclined to bleed). This is not necessarily a danger sign... I get it, because it's a common side effect of the birth control pill... but it is something you should mention when you go in for your annual pelvic exam and pap smear.

Second, the armpit lump. The odds are it is an ingrown hair. Try not shaving your pits for a few weeks and see if it goes away. If not, it's still probably just a swollen lymph node, but it's worth getting checked out by a doctor.

A little blood discharge after intercourse is normal. If your periods are irregular though, you should bring this up to your primary care doctor since its something that should be addressed. The lump under the armpit can be as innocent as a cyst but you can have a doctor look at it the same time you discuss the period issues.
