I had a period apirl 29 and are usually pretty regular on may 12-14th I went to see my husband in Delaware and we had unprotected sex. I also found out that I was ovulating at that time. Well may 26th I started spotting pink discharge and thought it was my period then later that day had brownish discharge. I had brownish discharge one time yesterday after I had a pulling like cramp and the same happen today minus the cramp... this wouldn't be my first pregnancy it would be my third so I took a home test this morning but it came out negative.. could I have took it to earlier or could it be something else
