hello everyone!

around the 15th of august i had unprotected sex with someone for about 3 days. he never ejaculated in me but im still worried about the sperm in precum possibly having found its way to my uterus. i had been on birth control steadily since about june. its been two week and a day since that happened and for these past two weeks i'd been feeling menstrual symptoms to no avail, until this sunday. i've been feeling queasiness and headaches for the past two weeks and a little bit of constipation.

im incredibly paranoid that the bleeding im experiencing now is implantation bleeding, although this has lasted fairly long, compared to most of my periods. i thought in the beginning that i was experiencing all of those symptoms as a way of my body reacting to being off the birth control. i havent had an opportunity to get a pregnancy test just yet, but until i do i felt i should get a second opinion before i worry myself to death.

any help or advice, suggestions are openly welcomed and greatly appreciated. Thanks!
