My last period was on Feb 1( this was my first period since a d&c procedure on jan 17). I had protected sex on Feb 7 and although there was no penetration my boyfriend ejaculated very close to my vagina if not next to it several times that same week. I tend to have an irregular period. On March 3 I had unprotected sex (starting without a condom and ending with one) and on March 4 I took a pregnancy test which came back negative. I would assume that rules out pregnancy as a result of the intercourse and close run ins that took place early in the month of Feb. As I still have yet to receive my period how likely is it that I am pregnant from those earlier incidents (prior to that of March 3)? Today I started taking Vitamin C as well as drinking parsley infusions. Advice?
