Early Pregnancy - not sure how far along???

Hi All,

I am new to the app and was hoping some of you other ladies may be able to help me out. So I have recently found out I am pregnant which is super exciting. My husband and I have only been trying for a couple of months. This is our first baby. I have endometriosis and was told I may have issues falling pregnant but obviously I am very lucky because it happened very fast.

So I can't work out how far along I am. I had my last period on 1st June and then started testing ovulation when it finished. I didnt ovulate until 20th June. I got my first positive pregnancy test 4 days before my period was due (took 2 tests and we're both very strong positive). I wasn't overly sure of the results as i had read that dome people had received false positives with the particular test I took which was forelife brand. So 4 days later I took another few tests which were also very much positive. So I scheduled a doctors appointment and was sent for a blood test which confirmed. Problem is my HCG levels were only at 92 and the Dr was worried the pregnancy wasn't viable. Have since had another follow up test 4 days later which revealed a rise in hcg levels but we're only at 387.

I know u usually count from the first day of ur last period but because I know ovulation date would it be more accurate to count from that date? I'm so confused and the doc only thinks I'm just 3 weeks pregnant. Anyone got some helpful advice?
