Lower pain left hand side early pregnancy

So.. before I fell pregnant I had been having some aches on my lower left side belly, wasn’t really sure what it was but left it as seemed to go away once I’d had a period.. it then came back about 1 week later ( this is before I conceived).. I am now  about 5 1/2- 6weeks pregnant and for the last 2 weeks I have been having that pain on my left hand side I feel like it has eased off but When I lean over things ect it gives me sharp pains usually on the left .. occasionally on the right .. I was just driving home when I sneezed and the whole bottom of my belly (pelvic area) got a really sharp pain ( gone within seconds) I’m just abit concerned has anyone had this before? I’ve only had 1 previous pregnancy which was a miscarriage at 6w5days ( I was bleeding from about 4 weeks so I new something was wrong) but I didn’t find out until 9 weeks I never got any of this pain before? I had a d&c could it be something todo with this , I’m abit concerned about ectopic but I did have the same pain before I got pregnant.
