Can I fall pregnant off the watery milky cm? I have had it the last 3 days with cramping in my hips I feel like maybe I've ovulated early.. and by the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I'm 4 days out from the fertility window and have had sex every day.. Some days multiple sessions.. But the last two nights my partner has only cum inside of me of me with what feels like just his tip :/ can the sperm still get where it needs to? This will be my 3rd baby but this is the first time of actually trying
