high estrogen in the 2ww as long as it is balanced with a good amount or high progesterone is good. It can be an early sign your body is trying to sustain 'something' because both of those hormones will be much higher than they are when not pregnant the whole pregnancy and fluctuate throughout. I dont know that it will pick it up on the OPK only because once you get a solid the internal state of the OPK should reset and will read your first test as a 'baseline' of hormones meaning you are more likely to get a low result and then another day you may get high if your estrogen is continuing to rise..but careful with those OPK's because you could also get a solid smiley from early early early HCG that will totally throw you off...LOL test reads HCG just like it does LH in your urine. it cant distinguish which is which.
eta: as someone who experienced first response 12 some years ago when they were still brand new pregnancy tests and technology i just want to add that i hate the curved handle ones too. I feel they are less sensitive actually. I know what the box and personal experience states and god knows i took one along with my digital this last BFP but i still hated that ANY digital could have such a for sure "YOU ARE PREGNANT YAY" and the curved handle FRER was a line SOOO squint worthy that if i had relied just on that i would have 100% not believed i was pregnant. It did look like an indent line, and i think thats why people dislike them. That and the fact the old ones caught the low levels of HCG and lines got VERY dark very quickly..i feel like they made the tests so they dont do that anymore. the test line is seemingly ALWAYS very light
