Question!

So, my period just ended Friday into Saturday and my husband and I had sex last night and he slipped it in for a few minutes maybe without a condom. He didn't sperm inside me.

But today I find that I am bleeding still. I wasn't bleeding yesterday just ending my period.

But today I am still bleeding a little. It's like pinkish red and light. implantation bleeding can't happen a day after, can it?

Somebody please help me!! ....I had my period June 21-27th and on July 2nd and by that point I was off my period for 5-6 days already I started bleeding bright red then pink brown and I told my sister and she said it could be implantation bleeding and ever sense then I been feeling cramps like mild cramps and throw upy and then on July 4th I started to bleed again bright red then pink brown then brown and by that point I was 7-8 days off my period still feel cramps from time to time and throw up...

Is it possible to not experience implantation bleeding? Or does everybody experience it?

I gotta question could I be pregnant and have 2 1/2 day period because I think i got pregnant on Nov 26 and had implantation bleeding on Dec 11 because I'm usually on my period for at least 4 days but mostly 5 or 6 which my full period was Nov 11 for 5 days ?? but in dec only 2 1/2 days it's kinda confusing really im excited about my Dr visit feb19 to know for sure :)

Ok i have a ? Me and my boyfriend had sex on yesterday and i bleed a little after then it stoped all day and the color was like a brown color and this morning i got up and I'm bleeding again my its a light pink color could this me implantation bleeding
