My period normally comes on time in  its monthly routine. Well I normally have my period on the 23 of every month and july I was late and I started late night 26th probably started an actual flow in the mid day of the 27th of July. I haven't started this month at all.  Also my boyfriend and I don't use any protection so he just nuts inside of me. Should I expect my period on the 27th or should I have expected it on the 23rd ? I just don't really know what I should aspect. Here my glow thing. Can someone please give me some insight on this
