Red spotting after Sex

Last night I had sex with my boyfriend and when I went to the bathroom I noticed pink tinged discharge. I was obviously freaking out but I didn’t feel any cramping. When I woke up this morning there was red spotting only on the toilet paper and not very much. Throughout this morning I felt cramping and it has me very concerned. I am 6 weeks 5 days and I don’t see my doctor until March 8.

Any reassurance or stories that would help me prepare?

I gave birth to my beautiful daughter November 2017 and I had a miscarriage in October 2014. So I am just extremely concerned that I am going to go through another miscarriage.

Thanks!
