I'm 30 weeks and we are 'doing it' maybe once or twice a week.
However, the past few times it has caused SEVERE BH. Last night I was genuinely worried I was going into labour after it.
It would be great if I was 39 weeks, but not 30 
Does this sound normal or should we discontinue intercourse?
I really don't remember this on my other pregnancies.
I feel fine this morning - no BH and baby moving as usual.
I would be waaaay too embarrassed to ask a midwife
