I don't recall having my period in September and i was supposed to get it around the 10th of sept, but i ended up having sex on the 23rd of september. The sex was protected and i don't think the condom broke nor that there was cum involved. I missed my period again this month, and symptoms of pregnancy have occurred such as sore breasts, nausea, and extreme headaches also the urge to pee a lot. Could i actually be pregnant, or am i just paranoid and my cycle could have been affected by the sex? btw my ovulation days are 21-25.
