Implantion or ectopic

So I had to go the hospital 18/12 with pains only had my positive test x 4 14/12 15/12 17/12 and one at hospital yesterday. They did virginal scan and couldn’t see anything so sent me for bloods hcg was 89. Midwife said she wouldn’t have seen anything on scan anyway with levels that low so I may just be really early on. I go back tomorrow for repeat but tonight I have this only when I wipe .... they are querying ectopic and trying to rule that out first. I have pain on the left side just under my rib.

I’m so worried to the point I’m dreading going to the hospital again tomorrow

Can anyone give any advice please
