Hi, I've been on the mini-pill (micronor) for three months now, the past two months I had regular periods and this month I haven't had a period at all. Me and my OH had sex one day before ovulation and I missed two pills over the weekend. 2 days after I experienced really light spotting which lasted only that day. My period was due on Monday 6th march and I thought I could feel myself coming on but it was just discharge I'm now 2 days late. Could this be pregnancy or is it just the pill?

Thank you :)
