Some Opinions??

My husband and I have been married for just a year and a few months now, he told me he's ready for a family so we started trying to conceive, but we stopped trying because we couldn't get pregnant. We decided to take a break, but lately I've been cramping ever since he came, not inside me, but on it and around it. I just played around and put some sperm inside with my fingers but I don't think it was even enough, rubbing it but since then I've been cramping a lot at first I thought it was because we had intimacy for a few hours nonstop but I also felt nauseated at some point, I saw a light pink spotting on a toilet (thought I was starting my menstrual) then the next day after wiping myself there was a light brown spotting there. It stopped hurting as much but today it's hurting again after another night of intimacy. I'm wondering if I conceived or it's because of the intimacy we've been having
