I had sex for the first time on Feb. 22 and I got my period on the 26th of that same month. I had sex again on March 3rd and used protection both times. My b/f told me he cummed while inside but it wasnt a big one - I dont know if thats considered pre cum or not. After I noticed a kind of dark brown liquid (it was the same form as natural lub when I got wet - I was bleeding again the second time so I dont know if it got its color from some blood) on my underwear.

I got my period on March 26th. My main concern here is if this really is a period or just implantation bleeding. Some websites say it happens 3-4 days after conception while other say it happend during the same time you expect your period - for 1-2 days.

Right now (the 28th) Im still having a "period" it looks like a natural red. The color is also a concern to me. Some say its pink or dark brown if its implantation. Is it drastically noticable (the color change)

Any advice, questions, or comments would be really helpful. Thanks

P.s - I have no tender breast or nipples or any pregnancy sympthoms so far
