I had unprotexted sex twice in one week. I used next choice twice 7 days apart (bad idea). The second time that I used it was a day after my original ovulation date. I had sex on the first day I was supposed to ovulate. Exactly 2 weeks later and 1 week before my period, I had a brown odorless discharge (not enough for a pantyliner) for 3 days then light pink spotting (only when i wipe) for two days. No other discharge at all. I was supposed to start my period 2 days ago but I havent seen it. Could I be pregnant???
