I had unprotected sex on day 10 of my cycle which was 14th April. I took p2 less than 12 hours later. I had no symptoms or side effects of p2. 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 cycle is usually about 24-28 days. But never less than 23. 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.
