3 recurrent miscarraiges and a year of infertility (anovulation) but Iโve just got a positive OPK!!๐ญ๐โค๏ธ

The test lines are all darker than the control line!๐๐ญ
Iโm so confused though as I just assumed AF was coming as Iโm so constipated and my breasts have been agonising, full and veiny. Iโm still in shock and DH has never been so happy since the birth our our daughter!

Question, has anyone ever got a positive opk but been pregnant? I am technically late for AF but again thatโs the norm for me but with the sign of AF due any second Iโm confused to how I have 4 positive opkโs?
Does anyone think that I could be pregnant? Iโve read a lot online that the LH and HCG are practically identical. This mornings test with FMU showed up so quick and so dark itโs making me think (hope) that I could be pregnant??
Please anyone who has experienced this please comment!
Honestly weโre cloud 9 right now๐ญ๐โค๏ธ
