It’s been 54 days since I last had sex (Feb 22) and I still haven’t gotten my period. Take note, he didn’t ejaculate inside. And I’m not sexually active, we just did it one time. I haven’t felt any early pregnancy symptoms and my pregnancy tests have been negative. I didn’t get my March period, but this month is supposed to start next week. There’s a slim chance I could be pregnant right? March was a pretty stressful month for me because of finals and school projects I had to get done. My sleeping pattern was off most of the time and I removed all carbs from my diet significantly.
