How long have you been TTC? And tips?

My fiancé and I have be. TTC for three months. This is our third month. AF came the 23rd of March, and lasted 4 days. Two days later I started spitting really light pink (which has never happened..) and I've had mild cramps for the past couple of days and felt bloated. But it would be way to early for me to be pregnant right? I don't know what's going on. But I have to be patient. How long has everyone else been TTC on here? Any tips?
