No CM but still can get pregnant?

Marina

Hey ladies! Been TTC for 7 months. For the HSG test with good results, I have been tested and I ovulate. So hoping for a BFP this month. I never have much CM and never EWCM. We use Preseed. However, I’m wondering how long sperm survives in me if I don’t have much CM. We have been BD the last 3 days, however I ovulate today and no BD because he works. Hoping that sperm will last in there to find the egg! Anyone get pregnant but doesn’t have much CM ?
