there are certainly some psychoanalysts, especially followers of Wilfred Bion, who believe that a lot of psychological conflicts occur prenatally. Some believe in 'cellular memory' going back to the time of conception, or possibly earlier.
Here's an example:

'I propose that the anguishing “feelings” experienced when one finds oneself lost in a crowd, the anguish of anonymity, of lack of acknowledgement, of not being noticed or perceived, of not standing out, of not being the chosen one; the experienced feelings of death, castration, engulfment, desintegration or feeling threatened of being “devoured”, sucked up, spoliated or exploited by “somebody else”, are situations in which the mind relives identificatory moments with fragments of its own past experienced by this branch of ours: partial experience — pertaining to our spermatozoid´s branch — which is thus evoked and re- edited...
(The egg) is much larger than the sperm<!--[if !supportFootnotes]-->[17]<!--[endif]-->. Its wait is also an anguishing one. Anguish referring to life or death, related with “the right time”: if it misses that proper moment, the encounter will become a mis- encounter. It will be dissolved and eliminated.
All this is registered by the cellular memory.
There is a variety of ways in which eggs accept mating. We know nowadays that some, “generously and tenderly”, hold out their “arms”, making the spermatozoid slide in. This will be a mating that will establish a pattern for heterosexual gentle, passionate relationships, of unconditional love. Others may be reluctant: they “know” – through genetically transmitted information – that as it is a foreigner whose genetic code is quite different from its own, “the shock of cultures” will be greater. They might then resist a bit [some resist more], they might try not to be disturbed in their immutability, fearing to accept that “foreigner”. '
(And a lot more in that vein)
