Been TTC since September. Been having regular sex as you do .. but last night after sex I noticed I was bleeding . This has never happened before. It wasn't loads but was (tmi) on the sheets and after I got all cleaned I had to change again as there was more in my pants . Also when I woke up there was more and when I wipe it's still pinkish. It's not a period bleed and like I said it's never happened before. I'm on CD 22 so period doesn't show until around day 28-34 .. could this mean anything ? I'm trying not to symptom spot and I know I'm prob just clutching at straws here. I've a slight cramp in lower back. Could this just be from sex ? It's never happens before and it wasn't different to any other time we DTD.. any similar experiences.??
