Baby Train

For those of you who are mothers: Me and my man are trying to get pregnant, I've been thrown off my period schedule due to dysfunctional uterine bleeding this year. I haven't been able to get pregnant the last 3 months and I was worried that I couldn't conceive. Now it's 2 days before my period, I've had no pms. I was wondering how long it took you guys to know when to test for pregnancy and any symptoms you noticed before the test.
