I have a headache, lower back pain , lump feeling in throat, fatigue , tender breasts and dizziness . My cycle is 22 days. I am now approximately 12 days DPO. I had unprotected sex all throughout my ovulation period as i am looking to conceive. I am gravida 1, para 0, elective abortion: 1. I just turned 43 yrs old. Could i be pregnant? When should I take a urine test?
