So I'm 5 days late on my period and I'm always on time I keep track every month to make sure it comes on time and it usually does. My boyfriend and I do not practice safe sex, I'm not on the pill, he doesn't use condoms, we just never had a problem and we've been doing this for 2 years. But now I'm scared my last period was june 11-16 and this months period was supposed to come on the 7th (I have a 28-30 day cycle) and it just never came I was having slight mood swings and slightly tender breasts and light cramping so I thought it would just be a day or two late and not to worry. Well its been 5 days now and a couple of hours ago I started bleeding brownish pinkish blood not a lot but not spotting either, so I put a panty liner on and after about 3 hours there was only like a dime sized thing of blood on the liner. But when I wipe its a little more blood but only pinkish. It went away for about an hour and a half and its starting again a little heavier but not a lot and I'm cramping and my boobs are even more tender. Please someone tell me this is just my period, I'm not trying to get pregnant (I mean if it happens it happens but I'm not intentionally trying to) could it be implantation bleeding or the late start to my period? I'm so confused.
