How far along would you estimate me?

I haven't had a period since late October (I'mstill breastfeeding my one years old). Two weeks ago I started getting morning sickness. I had to order my test online becaude I live in a small community and I didn't want anyone to know I might be pregnant. My test arrived and I just tested positive. I have this unfounded idea, or experience from previous pregnancies, that symptoms usually start around 4 weeks pregnant, and that would make me around 6 weeks pregnant. My obgyn doesn't see anyone until they are 12 weeks pregnant due to covid, but it's really hard for me to know. I really don't think I got pregnant in November, I would probably have showed symptoms before if that was the case. I've had horrible morning sickness with all my pregnancies. I know every pregnancy is different, but still. Do you think it is a good guess, or what would you think?
