These past three days I been having this clear whitish discharge along with mild cramps, and my period was expected to come yesterday but it never did. I'm starting to assume that I may be pregnant since me and my partner had sex using the withdrawal method (not our smartest idea) on the last day of my period last month, but we ended up switching to a condom after 3 minutes of fooling around. So I took two urine pregnancy tests; one 3 days before the expected period and one this morning when I woke up, and they both turned out negative. But lately I been experiencing breast pain, headaches, and I been going to the bathroom a lot at night. I usually have symptoms like this before my period, but what's making me concerned about it the most is the vaginal discharge because it's giving me false alarms of my menstruation coming. So based on all this info, could I be pregnant, and if not what else could be wrong? I know it's too much info but I'm just really curious and anxious about these unusual changes
