THIS IS KINDA TMI—-

I am currently a week late, yesterday when I wiped I had the littlest bit of brown discharge/blood so I put in a tampon, I went back to the toilet later on and took it out and it was only a little bit brown just like old blood. I put another tampon in expecting it to just be a little light period dince it was only the first day and again went back a few hours to take it out and it was bone dry. I didn’t put one in for the rest of the night and have had nothing at all. Even through to this morning I’ve had nothing. When I have a period it’s usually 7 days long and is always heavy. I’m a little worried to test as I always get my hopes up and then when it’s negative I feel like a failure . So the question I’m asking if has anyone else had this and it’s been implantation bleeding. I checked how far along I would be if I was pregnant and it would be around 5 weeks so is it possible to have implantation bleeding at 5 weeks? And if this has happened to anyone else we’re yous pregnant? Thank you ladies in advance x
