I am going through the same thing at the moment. I quit taking my birth control in april. I had breakthrough bleeding immediately after. I started that 7 day bleeding on march 30th or april 1st. Then, my now EX boyfreidn and I had sex on april 14th and 15th. He ejaculated inside me both times unprotected. Now, my period is still not here. Took a home pregnancy test. it was positive, but a lighter blue line. Looked almost faded. Now, I have been having certain symptoms in the last week or so. Tender, swollen breats with hard nipples almost all the time now, nausea, certain smells make my stomach turn, very tired and emotional, but it may be from the break up for now, light-headed and dizzy, and breaking out in sweats alot. I'm not sure what to do at this point. I want to go to the doctor and get a blood test, but i do not have medical insurance right now. So, I am just going to be good to my body and just wait it out and see.
