So am confused and don't want to jump the gun. Myself and my partner are TTC for two years. I had what I taught was my peroid on the 24th oct. It lasted 3 days. It was red and heavy for the first day and then became lighter after that. I feel nauseous, veiny boobs, odd headaches and tried. Just wondering has anyone ever had what they taught was their peroid to later find out they were actually pregnant???? Any advice or experiences would really help.
