Im new to this site and am not sure where is best place to post this but i have a question. I had my period on the 17th july so nearly 2 weeks ago and it lasted 5 days, the follwoing week i had unprotected sex a number of times with my boyfriend but realised even though i started my pill again that i had missed a day or two *stupidly* The past 3 or 4 days my breasts have felt very sore, kinda swollen and at some stages through the day and night have what i would describe as burning sensation along with the pain in my breast thats been causing me to feel very nauseous. I took 2 pregnancy tests yesterday even though it had only been a week or so since i had unprotected sex and they both said negative yesterday. Then today i started bleeding again and my boobs hurt a huge amount and i feel tired alot. Could i possibly be pregnant in that short time frame along with negative tests and bleeding?
