I had unprotected sex using withdrawal method on 27th of June. It was my 1st day of cycle which marks my 1st day of period. After 22 days, 19th of July, I had spotting which didn't last long. I usually have 35 and above cycle and 5 days on it is my period days, but sometimes 17-23 days, I haven't experienced yet the 28 days cycle. What would be the chances? Will i have my next period early this time? Thank you
