I had unprotected sex on day 10 of my cycle which was 14th April. I took postinor 2 less than 12 hours later. I had no symptoms or side effects of postinor 2. Just 3 days ago, my breasts started feeling sore just like they do before my periods. Today is day 25 of my cycle but I'm having blood from my vagina. I am yet to monitor its flow to know if it is implantation bleeding. My breasts have stopped feeling sore as of this morning too. My last cycle was 24 days, So I think I have had my periods on time, if it is my periods. Please guide me. Is this a good sign? Am I pregnant? When can I do a test? It's been two weeks since I was intimate.
