The first picture is the month I conceived but then miscarried... I had a super strong positive opk... which is unusual for me

the second picture is the month after mc (chemical) (this cycle) where you can see my peak is very low this time...which is actually what my peak has been the past 6 months I’ve been testing it never gets higher than this except for the month I conceived... basically I’m curious if you can still get pregnant with peaks like this if you have please drop your chart
