Hi, my husband and I had unprotected sex last Thursday and he came inside me a little. Im due for my period this week but I haven't received it yet. I'm not on birth control or any type of medication to prevent pregnancy. He came inside me before a little and I didn't get pregnant. I am having PMS symptoms like minor cramping, headache, dizzy sometimes and since yesterday my nipples are feeling tender. Im not sure if Im pregnant and cannot take a test yet as I hear its too early. We are not trying but will be thrilled if we are pregnant. Do you think I may be?

I used to be on birth control but stopped taking it since last April. We always have unprotected sex but he doesn't come inside me except these two times. Could I just be getting my period? Or pregnant?
