4 weeks with FRER changes. Help!

Katie

I hope I’m posting this in the right group.

I had a chemical pregnancy in January, had a normal period in February and then we started TTC. AF was due 3/17, and even though I sometimes have long cycles, I couldn’t wait to test. I got a BFP on 3/17 (pic below).

So that makes me just over 4 weeks pregnant. The last few days, I’ve been queasy off and on but this morning I was truly nauseous. Idk what possessed me, but I took another test and as you can see in the pic below, the test line is darker than the control line:

Is this good/bad/normal? I poked around online for answers but am looking for support I guess. I haven’t called my OB yet, was gonna hold off another week or so. I know the only way to accurately track things this early is with serum HCG but I’d prefer not to have blood work done at this time if I can avoid it.

Any advice you all can offer would be greatly appreciated. Thank you!
