We had sex the night before my fertile window opened. My period is due in 2 days, this coming Tuesday. I always spot before my period and I have had nothing. But I have had some strange symptoms that could lead me to believe it's possible. I have a son and know what it could feel like but I also realize those symptoms could mean other things. Just looking for opinions as it is a pressing issue on my mind. Did have spotting during ovulation, but not necessarily implantation bleeding. The no spotting pre period is making me recall all the other "symptoms" that might add up to a bun in the oven.
