*trigger warning*

No sac seen on ultrasound at 6weeks. Looking for advice from others who have had the same.

I have one baby almost 7 months now on the 28th of December. The first day of my last period was a November 6th and I was supposed to get my period December 4th but haven’t gotten it as of yet. I’ve tested a few times and 4/5 days after my missed period I had very faint line and then took another few and they’ve gotten quite a bit darker since. I had a tiny bit of blood when I wiped twice the day before yesterday and yesterday so I went for an ultrasound to make sure everything was okay (according to my period I should be 6w1d at that ultrasound) and the tech did a stomach and internal ultrasound. She said she didn’t see a sac and asked if I could be earlier in the pregnancy and if my periods are normal. Most of them are 28 days but some have been 30,31 days here and there. So I’m kind of paranoid now that I’m having an ectopic pregnancy because she said by now unless I’m earlier on I should see a sac. I didn’t have these issues with my first. I have period like cramping or even minor than that (like I did with my first). Has anyone had an ectopic and can give me some advice what I should be looking out for? I got my blood taken too and I’m hoping my doctors office will have the results tomorrow. But I’m nervous and don’t know what to think. Everything I’m reading points towards ectopic if there isn’t a sac.
