Hi,

I had my period April 20th, no sight of blood or anything till 43 days later June 1st which was suppose to be my ovulation time it was blood for 2 days then turned brown for 3 days. Done a few pregnancy regular and early detect. Test that says negative. Did I test too early? My period has always been on time never very late. All of May no period. Help or suggestions please? Thanks in advance.
