Has your sex life changed during pregnancy??

Mine has plummeted! We’ve gone from having sex daily, sometimes twice or three times a day to barely having it at all. In the really early stages of my pregnancy (3 or 4 weeks) we had sex and I was met with a really dull ache in my lower stomach right afterwards and a teeny bit of spotting so we stopped having sex for a while. Im now 15 weeks and we tried again last night and although I enjoyed it, it hurt at times and this ache is still there straight after ☹️ for such a sexual person this is frustrating, my boyfriend is a saint and completely understanding and never makes me feel bad if I don’t want to have sex but I know the sudden drop has effected him, it would effect anyone!! Just wanted to know if I’m alone on this one...
