Hi can any one please advise/comment.. My LMP was 22nd June which lasted about 4-5 days I had unprotected sex on 28th June and 2,3 and 5th July (yes we're trying) and on 6th July I had a slight pink tint when I went to toilet and wiped (sorry if tmi) then I had cramping on 7th July and today 10th July had slightly mire pinkish/red blood when wiping.. Your comments and thoughts would be appreciated as to what it could be down to. My cycle is every 27days so roughly due my next period on 18th or 19th July..
