I just need reassurance

I have a head cold or something right now but the past couple days I e also been bleeding a little. It started as spotting which is normal and I also assumed when we had sex it was just a little too rough but yesterday I had a couple blood clots and I had some mild cramping, nothing worse than what I've been dealing with. Well I took a test this morning just to play it safe and the second line is super faint, granted it's supposed to be the control line. I guess I'm just confused and it's my first pregnancy so I want everything to be okay...
