I currently believe I’m pregnant but my body builds HCG very slowly. I’ve had two previous pregnancies and both didn’t show up till I was 2 and 1/2 months. I’ve taken a pregnancy test and it has obviously comes up negative as I’m likely only 5 weeks.

Can anyone recommend a way to check? I’m going to ask my gp for a pregnancy blood test but they normally don’t like doing (had it done once before when I was getting other bloods done as I was 3 months late (I have PCOS)).
