Should I Be Worried

So I had 2 blood draws last week and my hcg was increasing and an ultrasound showed a gestational sac but since I’m only 4 weeks there wasn’t much to see. I had 2 minor spotting incidents, once after sex, and the other after the transvaginal ultrasound. It was small pink spots that only came when I wiped and tapered off after a couple hours. This morning I felt I needed to poop but couldn’t and strained a little to see if I could get it out (tmi) and after failing to poop, I wiped and there were 3 small spots of spotting. I just wiped again and it’s back to nothing but just was worried.
