So my last period was 13/10/18-16/10/18. My app said I was ovulating on the 30/10/18 but I had unprotected sex everyday from the 26/10/18 until the 4/11/18. Over the last couple of days I have been feeling exhausted, waves of feeling sick but not being sick, constipation, cramping , bloating and my nipples being a little to sensitive. my hair getting greasy after 1 day of washing. 2 days ago I experienced what seemed to be implantation bleeding, it was very light pink but didn't look like blood, since this morning 11/11/18 it has turned red, my period is not due until the 14/11/18. I have never came on early, I'm either on time or I am late. I have taken tests but they are coming back negative, I am still feeling as if something is happening with my body. Has anyone had this and had a BFP??
