I had unprotected sex (no ejaculation inside) for like 30 seconds (towards the end, after my partner had already ejaculated twice using protection) 2 days before my period. I got normal period after 2 days. 20 days after that I got a CBC and Typhoid test done among other tests because I got very sick. Typhoid was positive but I was looking at the RBC, MCV and MCH and noticed that my RBC count was slightly high {(4.89) lab range: 3.80 - 4.80 } but MCV and MCH were slightly low {(81.40) lab range: 83- 101 and (25.70) lab range: 27 - 32 respectively}. Ik this might happen in pregnancy. It's now been 3 weeks and 1 day since that sexual intercourse. My periods are due after 9 days. Should I get a at home test or a pregnancy blood test? Do you think there are chances of a pregnancy in this scenario?
