Hey hun sorry your going through this I know it's hard but try not too worry too much (easier said then done) but talking from personal experience I bled at 4 weeks, 8 weeks & 11 weeks, my MW said you wouldn't believe how many women bleed especially early pregnancies and many of them go on to have very healthy babies, it could be brearthrough bleed which is normally around the time of your expected period? Could be due to your cervix being irritated during foreplay or intercourse? Just monitor the bleeding, and if your still worried ring the EPU or a MW and they will talk too you regarding the bleeding, also try not too do another test if you can as that's what I did I did one and the positive line was darker than control but week later it was a lot lighter than control line and I was around 6 plus weeks as normally that's when your levels are too high and the pregnancy test can't read it properly so makes the line later (called the hook effect) as levels are too high, xx
