Hi ladies, I hope there are people who can help here or any Doctors here:

So my boyfriend and I have been trying for +- 7 months now and the week of the 11th of Feb (Thursday) we did it twice on that night and he told me he ejaculated x7 in me, so a week and a little went by and on the 22nd I started spotting and then took a test on the 26th of Feb and it said negative, my mum says that sometimes it can say that even though you show all the symptoms. What do YOU GUYS THINK? am I pregnant or must I go get checked out, cause the 13th of Feb it was my fertile day and a man's cum lasts 5days inside a woman's body. We are trying so hard to stay positive and all to have a baby.
