Guys???

So I’m currently 7weeks and 6days today I had slight pink that I wasn’t 100% on was pink around lunchtime that was after moving some heavier things (due to my job) but this evening after sex (with a orgasm) I noticed a pink tinge. Dude you think it’s a sign of a miscarriage or just to much physical stuff? One is with flash other is not and that’s not so much from just wiping it was actually feeling inside.
