I’m 6 weeks and been spotting on and off since 14dpo. My hcg levels rised from 88 to over 4000 in 7days which was faster than W.E expected an ultrasound showed 5 week sac and yolk. Back in a few days to hopefully see a 6 and a half week baby and heart beat however spotting again with cramps!!! It all began immediately after sex this time. Any ideas why? Didn’t happen in my last pregnancy
